REMOVAL & INSTALLATION



1967-68 Chevy II
  1. Siphon off 2 / 3 of the brake fluid from the master cylinder.
  2.  

The insertion of the thicker replacement pads will push the caliper pistons back into their bores and will cause a full master cylinder to overflow.

  1. Jack the car up and support it with jackstands. Remove the wheel(s).
  2.  
  3. Extract and discard the pad retaining pin cotter key.
  4.  
  5. Remove the retaining pin and remove the brake pads.
  6.  
  7. Force the caliper pistons into their bores with a putty knife and install the replacement pads.
  8.  
  9. Install the retaining pin and insert a new cotter key.
  10.  
  11. Refill the master cylinder and bleed the system if necessary.

  1. Siphon off 2 / 3 of the brake fluid from the master cylinder.
  2.  

The insertion of the thicker replacement pads will push the caliper piston back into its bore and will cause a full master cylinder to overflow.

  1. Jack the car up and support it with jackstands. Remove the wheel(s).
  2.  
  3. Install a C-clamp on the caliper so that the solid side of the clamp rests against the back of the caliper and the screw end rests against the metal part of the outboard pad.
  4.  
  5. Tighten the clamp until the caliper moves enough to bottom the piston in its bore. Remove the clamp.
  6.  
  7. Remove the two allen head caliper mounting bolts enough to allow the caliper to be pulled off the disc.
  8.  
  9. Remove the inboard pad and dislodge the outboard pad. Place the caliper where it won't be supported by the brake hose.
  10.  
  11. Remove the pad support spring clip from the piston.
  12.  
  13. Remove the two bolt ear sleeves and the four rubber bushings from the ears.
  14.  
  15. Brake pads should be replaced when they are worn to within 1 / 32 in. of the rivet heads.
  16.  
  17. Check the inside of the caliper for leakage and the condition of the piston dust boot.
  18.  

To install:

  1. Lubricate the two new sleeves and four bushings with a silicone spray.
  2.  
  3. Install the bushings in each caliper ear. Install the two sleeves in the two inboard ears.
  4.  
  5. Install the pad support spring clip and the old pad into the center of the piston. You will then push this pad down to get the piston flat against the caliper. This part of the job is difficult and requires an assistant. While the assistant holds the caliper and loosens the bleeder valve to relieve pressure, you get a prybar and try to force the old pad in to make the piston flush with the caliper surface. When it is flush, close the bleeder valve so that no air gets into the system.
  6.  

On models with wear sensors, make sure the wear sensor is toward the rear of the caliper.

  1. Position the outboard shoe with the ears of the shoes over the caliper ears and the tab at the bottom engaged in the caliper cutout.
  2.  
  3. With the two shoes in position, place the caliper over the brake disc and align the holes in the caliper with those of the mounting bracket.
  4.  


WARNING
Make certain that the brake hose is not twisted or kinked.

  1. Install the mounting bracket bolts through the sleeves in the inboard caliper ears and through the mounting bracket, making sure that the ends of the bolts pass under the retaining ears on the inboard shoe.
  2.  
  3. Tighten the bolts into the bracket and tighten to 35 ft lbs. Bend over the outer pad ears.
  4.  
  5. Install the front wheel and lower the car.
  6.  
  7. Add fluid to the master cylinder reservoirs so the fluid level reaches 1 / 4 in. from the top of the reservoir.
  8.  
  9. Test the brake pedal by pumping it to obtain a "hard" pedal. Check the fluid level again and add fluid as necessary. Do not remove the vehicle until a "hard" pedal is obtained. Bleed the brakes if necessary.
