Front Rotors and Brake Pad Replacement

Category: 

TOOLS
 

  • 14mm Socket
  • 17mm Socket
  • Wire Brush
  • Wire Coat Hanger
  • Jack Stand(s)
  • Mallet or (Hammer and a piece of wood)
  • Wheel chock
  • Brake Pad Separator or (C-clamp)
  • Brake Grease
  • Isopropyl Alcohol
  • Brake Cleaner

PROCEDURE (Driver-side front brake)

1. Loosen Lug nuts

2. Put the car up on jack stands, chock rear wheels, and remove the front wheels.

3. Remove both Main Pin Bolts -- 14mm. These are the bolts holding the Caliper onto the Torque Member/Bracket.

4. Slide the Caliper off and hang it on the coil of the spring. (I cut off a piece from a wire coat hanger).

5. Some recommend removing the Brake Pads at this point. However, you must note to the way the pads are seated in the metal Pad Retainer in the Torque Member/Bracket for installation on new pads. Having corrosion build-up between the brake pads and the metal Pad-Retainers I removed the Torque Member/Bracket with Pads still in place.

6. Remove both Torque Member Fixing Bolts -- 19mm. These bolts hold the Torque Member/Bracket onto the Steering Knuckle. Picture below is with the Torque Member removed. (See also picture for Step 12.

7. Remove the old Rotor. If Rotor is stuck, use a mallet or a hammer with a piece of wood against the rotor. Tap against the inside of the Rotor, rotate and repeat as necessary.

8. Installing new Rotor -- Use a clean rag and isopropyl/rubbing alcohol to wipe the thin layer of packing grease off the Rotor. Also, if the old Rotor was stuck, clean the hub face with a wire brush. If you opt to apply some grease to prevent the new Rotor from rusting onto the hub face, do so minimally. Install new Rotor and hold in place with lug nuts.

9a. Prep brake hardware (Shims and Retainers)-- Note orientation and placement of Brake Pad Shims. Remove and clean the inner and outer Brake Pad Shims of each Brake Pad.

9b. Remove metal Pad Retainers by placing finger behind the lower part of the retainer and push up and out. With a wire brush, clean the area of the Torque Member/Bracket where the metal Pad Retainers sat. Install the metal Brake Pad Retainer and apply grease to the channel where ends of the Brake Pads ride.

10. Prep and install new Pads -- Ensure that you apply a liberal amount of brake grease between the Brake Pad, inner-, and outer-Brake Pad Shims. Install Brake pads and ensure placement in metal Pad Retainer.

11. Compress caliper piston -- Loosen brake fluid reservoir cap. Wrap cloth around the reservoir and maybe a container underneath to catch any overflow. Using a brake caliper spreader (see picture) or C-clamp and the old Brake Pad (set against the piston), compress the Caliper Piston and watch for brake fluid overflow.

I had to remove over 100cc of brake fluid to accommodate new rotors and pads for all 4 wheels.

12. Install Torque Member/Bracket -- 19mm.

13. Install the Caliper's Main Pin Bolts -- 14mm.

14. Install Wheel and tighten lug nuts.
