How to change brake pads is simpler than replacing rear disc brakes, and if you have experience doing basic repairs the job will take about 4 hours. Drill it out. Let the penetrant work for about 15 minutes. Then remove the screw (Photo 4) and pull the rotor off the hub. Light film of brake grease. Install new anti-rattle clips. New anti-squeal shims, apply disc brake grease to the inside of the shim before installation. Inner pad with the wear indicator facing upwards. Two pad guide pins. Anti-rattle springs and the clip. Fill the reservoir with fluid and bleed the brake system. Adjust the parking brake if necessary. Replacing Disc Brakes & Pads. This how-to was originally posted on. New brake discs & pads. Ask for Kelsey-Hats anti-rattle clips. ” Tighten the two Allen bolts to 25Nm and you are done. Pump the brake pedal a few times, put the wheels back on and go for a drive. Be careful, as for the first. 9: Remove the front brake pad from the caliper. Click image to see an enlarged view. 10: Remove the inner pad and anti-rattle clip, do not forget to install the clip on the new brake pads. Most brake shoes contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake.

Caliper Guide Pins If the caliper is not free to move, the culprit might be bent or binding mounting pins. Even if guide pins are not damaged, swollen or hardened guide seals or lack of lubrication may cause the caliper to bind resulting uneven pad wear. Always inspect all mounting surfaces and hardware for corrosion, wear or misalignment. Replace all mounting hardware and install a replacement caliper using the proper caliper lubricant. Abutment Clips Abutment clips reside on the caliper bracket lands on most vehicles. They create a uniform surface for the pads to make contact with. Some abutment clips include fingers that hold the pad in place.

These are consumable components in a, not only because of rust and wear, but because the anti-rattle features can fatigue over time. New abutment clips are being used on some new vehicles that help to push the pads back from the rotor to reduce drag and allow for less wear on the pads and rotors. Comtrend Ct 301 Manualidades. Failing to renew these components as part of a brake job could reduce the life of the brake job and increase comebacks. Caliper Guide Pin Boots Most floating brake parts and use a rubber or plastic insulator or shim around the mounting bolts of the caliper. This sleeve of soft material loses resiliency over its lifetime.

This is hastened by the high-temperature environment of the brakes. As materials wear, instead of being round they are flattened by the torque from the brakes into an oval shape that can cause excessive caliper movement. This can cause noise like rattles and thumps even if the brakes are not applied.

Always inspect and replace if necessary any dust boots or grommets that protect caliper bolts or slides. If the soft parts look OK, clean out all the old lubricant and replace with new lubricant.

Unlike steel, soft parts like rubber are sensitive to chemicals. Choosing the right lubricant for these parts is critical to ensuring the integrity of the part. If the caliper boots fail to make a seal with the caliper bracket and bolt, water can be sucked into the cavity as the bracket contracts and cools.

Anti-Rattle Clips Heating and cooling cycles can weaken springs and anti-rattle clips. Weak parts can result in excessive caliper/pad movement or binding causing noise and other related problems. This can lead to uneven and premature pad wear, rotor wear and pulling. On some floating calipers, the most neglected piece of hardware is the clip in the bridge. Shims Insulating the brake pad from the caliper can be done two ways.
