Replacing the front brake pads on a 2017 Honda Fit is a critical maintenance task that ensures safety, restores performance, and can be accomplished by most DIY enthusiasts with the right tools and knowledge. This comprehensive guide provides definitive, step-by-step instructions for diagnosis, replacement, and post-installation care, drawing on proven automotive repair principles. By following this advice, you can confidently manage this repair, avoid common pitfalls, and maintain your vehicle's braking system effectively. The process involves recognizing wear signs, gathering correct parts and tools, executing the physical replacement safely, and properly bedding in new pads for optimal function.
Understanding the Brake System in the 2017 Honda Fit
The 2017 Honda Fit utilizes a front disc brake system, which is the standard for modern vehicles due to its superior stopping power and heat dissipation. The front brakes typically handle a majority of the braking force, making their maintenance paramount. The central components involved in this guide are the brake pads, calipers, rotors, and hardware. Brake pads are friction materials clamped onto the rotors by the calipers to slow the vehicle. Over time, these pads wear down, reducing their thickness and eventually compromising braking efficiency and safety. Knowing how this system works is the first step to proper maintenance. The Fit’s design allows for relatively straightforward access to the front brake assemblies, facilitating easier inspection and replacement compared to some other vehicle systems.
Identifying Signs of Worn Front Brake Pads
Recognizing when your 2017 Honda Fit needs new front brake pads is crucial for preventing damage to more expensive components like rotors and for ensuring safe operation. Several clear indicators signal excessive wear. Audible warnings are often the first sign. Many brake pads, including some OEM versions for the Fit, have built-in wear indicators that produce a high-pitched squealing or chirping noise when the pad material is low. This sound is distinct and typically occurs when braking. Ignoring this can lead to a grinding or growling noise, which indicates the pad material is completely worn and the metal backing plate is contacting the rotor. This is a severe condition that requires immediate attention to avoid scoring the rotors.
Reduced braking performance is another key sign. You may notice that the car takes longer to stop, the brake pedal feels softer or sinks closer to the floor, or the vehicle pulls to one side during braking. A vibration or pulsation in the brake pedal during application often points to warped rotors, which can be caused by excessively worn pads overheating the rotor. The most reliable method is a visual inspection. You can often see the brake pad through the openings in the wheel. On the 2017 Fit, a pad thickness of less than 3mm (approximately 1/8 inch) generally means replacement is due. Checking both front wheels is important, as wear can sometimes be uneven.
Gathering the Necessary Tools and Parts
Before starting the replacement, assembling all required items streamlines the process and prevents interruptions. For parts, you will need a new set of front brake pads specifically for the 2017 Honda Fit. Choices include OEM (Original Equipment Manufacturer) pads from Honda or various aftermarket options (ceramic, semi-metallic, organic). Ceramic pads are popular for their quiet operation and low dust, while semi-metallic pads may offer better performance in varied conditions. It is often advisable to purchase a brake hardware kit or pads that include new clips, shims, and springs. Reusing old hardware can lead to noise and improper caliper function. Inspecting the rotors is also essential; if they are deeply grooved, scored, or below minimum thickness, they should be resurfaced or replaced concurrently.
The basic tool list includes a jack and jack stands rated for your vehicle's weight—never rely on a jack alone for support. A lug wrench or torque wrench is needed for wheel removal. A C-clamp or brake caliper piston tool is necessary to compress the caliper piston to accommodate the new, thicker pads. A socket set (typically 12mm, 14mm, 17mm, and 19mm sockets are useful for the Fit), ratchet, breaker bar, pliers, and a flat-head screwdriver will handle most bolts and clips. Gloves and safety glasses are essential for personal protection. Having a wire brush for cleaning the caliper bracket and a brake cleaner spray to remove dust and debris is highly recommended. Fresh brake fluid might be needed if the reservoir level is too high after piston compression, as it can overflow.
Safety First: Preparations Before Starting Work
Safety is the absolute priority when working on any vehicle, especially the braking system. Always park the car on a level, solid surface like concrete or asphalt. Engage the parking brake and place wheel chocks behind the rear tires. Loosen the front wheel lug nuts slightly while the car is still on the ground, as they can be very tight. Use the jack at the manufacturer's specified front lift point (clearly indicated in the owner's manual or on the vehicle's pinch weld) to raise one side of the front end. Once lifted, immediately place a jack stand under a secure structural point, such as the designated stand point or a reinforced section of the frame, and lower the car onto it. Double-check that the stand is stable before proceeding. Repeat for the other side if you are doing both front brakes simultaneously. This two-support system (jack stand as primary, jack as secondary backup) is non-negotiable for safe work.
Step-by-Step Removal of Old Brake Pads
With the vehicle securely supported, remove the lug nuts and take off the front wheel. This provides full access to the brake caliper and rotor. The brake caliper is the clamping assembly that holds the pads. On the 2017 Fit, it is typically mounted with two guide pins or slider bolts on the back. These are often 12mm or 14mm bolts. Use the appropriate socket to remove the lower guide pin bolt first. Sometimes, the upper bolt acts as a hinge; you may only need to remove the lower bolt and pivot the caliper upward. Alternatively, remove both bolts for full caliper removal. Carefully lift the caliper off the brake rotor. Do not let the caliper hang by its rubber brake hose, as this can damage the hose internally. Suspend it securely with a bungee cord or wire from the suspension spring or other solid component.
Once the caliper is out of the way, the old brake pads can be removed from the caliper bracket. They may be held in by retaining clips, springs, or pins. Note their orientation for reassembly. The inner and outer pads might be different shapes. Use a flat-head screwdriver or pliers to gently pry out any anti-rattle clips. With the pads removed, this is the perfect time to inspect the rotor surface for deep grooves, cracks, or uneven wear. Thoroughly clean the caliper bracket where the new pads will sit using the wire brush and brake cleaner. This removes rust and debris that can cause the new pads to stick or wear unevenly. Also, inspect the rubber caliper bushings and dust boots for tears or deterioration.
Compressing the Caliper Piston
A crucial step before installing new pads is compressing the caliper piston back into its bore. The piston has extended over time as the old pads wore down, and space must be created for the thicker new pads. Open the brake fluid reservoir cap under the hood to relieve potential pressure, but cover the opening with a rag to prevent contamination. Place the old brake pad or a small block of wood against the piston face inside the caliper. Use a large C-clamp or a dedicated brake caliper tool, spanning it from the back of the caliper to the pad/wood block. Tighten the clamp slowly and evenly. You will see the piston retract. If the piston is difficult to compress, ensure the brake fluid reservoir isn't overfull; you may need to siphon some fluid out to prevent overflow. On some vehicles, the piston must be rotated while compressing if it has an integrated parking brake mechanism, but the 2017 Fit's front calipers are typically a simple push-back design.
Installing the New Front Brake Pads
Begin by applying a thin layer of high-temperature brake grease or anti-seize compound to the back plates of the new brake pads (where they contact the caliper piston and bracket) and to the contact points on the caliper bracket. Do not get any grease on the friction surface of the pad or the rotor. This step minimizes brake squeal and ensures smooth operation. Install any new shims, clips, or springs that came with the pad set onto the caliper bracket, following the kit instructions or your earlier orientation notes. Slide the new pads into place on the bracket. They should fit snugly but move freely without binding.
Now, carefully position the caliper assembly back over the new pads and the rotor. This may require some wiggling as the piston must align perfectly with the back of the inner pad. Once seated, hand-thread the caliper guide pin bolts back in. Before final tightening, ensure the caliper can float slightly side-to-side; this is its normal operation. Torque the guide pin bolts to the manufacturer's specification. For the 2017 Honda Fit, this is typically around 25-30 ft-lbs (34-41 Nm). Refer to a service manual for the exact value. Over-torquing can damage the bolts or bushings. Repeat the compression and installation process for the other front brake assembly if replacing both sides.
Reassembly and Final Checks
After the calipers are securely bolted on, reinstall the wheels. Hand-tighten the lug nuts in a crisscross pattern before lowering the vehicle. Once the car is back on the ground, use a torque wrench to tighten the lug nuts to the proper specification, which for the Honda Fit is usually 80 ft-lbs (108 Nm). This ensures even clamping and prevents warping. With the wheels on, pump the brake pedal several times before starting the engine. The pedal will feel very soft and may go to the floor on the first few pumps. This is normal as you are moving the pistons back into contact with the pads and building hydraulic pressure. Continue pumping until the pedal feels firm and high.
The Bedding-In Process for New Brake Pads
New brake pads require a proper bedding-in or break-in procedure to transfer a layer of friction material evenly onto the rotors. This maximizes braking performance and prevents glazing or uneven wear. After confirming a firm brake pedal, find a safe, empty stretch of road. Accelerate to about 45 mph, then moderately apply the brakes to slow down to around 10 mph. Do this firmly enough to feel significant deceleration but not so hard as to engage the anti-lock braking system (ABS) or come to a complete stop. Repeat this process 5 to 10 times, allowing about 30 seconds of driving between cycles to let the brakes cool slightly. Avoid coming to a complete stop during this sequence. After the last cycle, drive gently for several minutes without using the brakes excessively to allow them to cool completely. This process ensures optimal contact and performance from the new pads.
Post-Installation Maintenance and Monitoring
After the initial bedding-in, monitor your brakes closely for the first few hundred miles. Avoid hard, panic stops for the first day unless absolutely necessary for safety. It is normal for new pads to have a slight smell during initial use and to produce more brake dust as the surfaces mate. Listen for any unusual noises; minor squeaking can occur but should fade. Check the brake fluid level in the reservoir; it should be between the MIN and MAX lines. After a week of driving, visually inspect the pads through the wheel to ensure they are seating correctly. Regular maintenance, such as cleaning brake components during tire rotations, can extend the life of your pads and rotors. Remember that driving habits heavily influence brake wear; aggressive city driving will wear pads faster than gentle highway commuting.
Troubleshooting Common Issues After Replacement
Even with careful installation, minor issues can arise. If you experience a persistent squealing noise, it may be due to vibrations. Verify that all shims and anti-rattle clips were installed correctly and that grease was applied to the pad backing plates. Ensure the pads are not dragging; the caliper should slide freely on its guide pins. A soft or spongy brake pedal after bleeding is not typically required for a simple pad swap unless the brake line was opened. It usually indicates air in the system, which may have been introduced if the brake fluid reservoir ran dry during piston compression. This may require a full brake system bleed. If the car pulls to one side, it could mean a stuck caliper piston or that the pads on one side are not making full contact. Re-inspect the installation on that side. Excessive brake dust is often a characteristic of certain pad materials, like semi-metallic compounds.
When to Seek Professional Help
While this guide equips you to handle the pad replacement, recognize when a job is beyond a DIY scope. If during inspection you find severely damaged or warped rotors that need machining or replacement, and you lack the tools or experience, a shop may be better. If the caliper piston boots are torn or the piston itself is seized and won't compress, the caliper may need rebuilding or replacement—a more advanced task. Any signs of brake fluid leaks from the caliper, hose, or master cylinder demand immediate professional attention. If at any point you feel uncertain about the safety of your work, consulting a certified mechanic is the wisest choice. Your safety and that of others on the road is paramount.
