Fixing the Failing Brakes Using a Mazda Brake Disc and Pad Kit
Don't let the pads wear out too thinly, up to the point wherein the metal backing plate of the pad is the one touching the rotor surface. This will ruin the rotor with heavy grooves on the surface, compromising your Mazda's braking power. If the disc and the pad are already worn out, do the necessary brake repair or service. With a complete Mazda brake disc and pad kit, you can replace the faulty brakes in no time. Here's a quick guide:
Difficulty level: Moderate
Things you'll need:
- Hydraulic jack
- Jack stands
- Pry bar
- 3/8-inch ratchet
- 3/8-inch sockets (assorted)
- 3/8-inch assorted extensions
- 1/2-inch ratchet
- 1/2-inch sockets (assorted)
- 1/2-inch breaker bar
- Open-ended wrenches (assorted)
- Torx sockets (assorted)
- Hex sockets (assorted)
- Reverse Torx sockets
- Wire brush
Step 1:Loosen the lugs. Use the ½-inch breaker bar and set them to the appropriate socket size. Turn this counter-clockwise until the lugs are loose enough. Don't remove them yet.
Step 2:Lift the vehicle off the ground using the hydraulic jack. Place this either on the frame rail or the jacking points on the side of the vehicle. Use jack stands underneath the vehicle for support. After raising the vehicle, you can now remove the wheel as you finally undo the lugs that secure it.
Step 3:Unscrew the caliper. Remove the bolts on the caliper to slide this out. If the caliper won't slide out that easily, you may use a pry bar or flathead screwdriver to work on it. Let the caliper rest on the suspension. You now have to undo the bolts on the rear of the hub to unlock the caliper carrier. If this is too tight, you can use a breaker bar with a mallet or an impact gun to remove it.
Step 4:Remove the old brake disc/rotor. The discs will pop out with a few good strikes from a hammer. Some discs, however, may have screws that you have to remove for them to come out. Once the disc is safely removed, install the new brake disc or rotor. Set the disc properly and then secure it with lug nuts using an open-ended wrench. Tighten down the rest. A brake cleaner or degreaser can be used to remove the oily packing residue from the disc.
Note: If there's rust on the hub, remove this using a wire brush. WD-40 may also be used. Do this before installing the new disc.
Step 5:Re-assemble the carrier. Secure it with the bolts, which should be tightened using an impact gun or a breaker bar. The caliper should be compressed. With a C-clamp, compress the caliper piston. The piston should be level with the caliper housing. The cap should be off the brake reservoir to prevent blowing a line.
Step 6:Install the new pad to replace the old one. The new pad must be installed in the carrier to replace the old one. Apply some anti-squeal grease on outside of the pad. After this, you may now set the bolts on the caliper. Make sure that the caliper is able to move without binding. Once you're sure about its placement and movement, tighten the bolts.
Step 7:Put back the wheel. While the vehicle is raised, you have to tighten the lugs. After you bring the vehicle back to the ground, torque the bolts using a torque wrench or a breaker bar.
Do the same steps for the rest of the wheels. After installing the brake disc and pad kit, you have to pump the brakes several times to check on the pressure. Also take time to break-in the pads and the rest of the braking system.
