  1. DISC BRAKE OVERHAUL

  2. Couple of things to think about when working on brakes. 1. Some ones life may hang in the balance if you do a poor or second rate job. 2. If you do not think a part will work right replace it. 3. Always put in new brake pads, if the hardware has problems replace it and if the caliper or piston is worn or pitted replace it. And last but not least inspect the hose for wear and cracks.

  3. Jack up car and place safety stands in an appropriate placeRemove wheel

  4. remove wheelcheck wheel studs and lug nuts(replace if necessary)

  5. remove caliber and brake padscheck rotor for run out

  6. mike rotor for Thickness variations

  7. if rotor needs to be turned, look up proper procedures on how to remove before removing

  8. Inspect brake lines and hoses

  9. If car has very many miles or if seal looks bad or piston rusted, replace the caliber assembly

  10. Replace with a loaded caliper (ones with brake shoes in) Another option is to rebuild the caliber

  11. to rebuild caliber

  12. 1. Remove bleeder screw and make sure passage is clear this is the first step if we have a problem we need to replace the screw or the whole caliper.

  13. 2. Removing piston out of caliper

  14. Ways of removing piston out of the caliper1. Hydraulic pressure, just take caliper off of rotor, set over a pan to catch the brake fluid and step on the brake until it comes out

  15. Air pressure - take caliper off and use a air nozzle to blow it out of its bore CAUTION if fingers are in the way you might lose them be careful You can also break the piston

  16. Hone the cylinder if piston is pitted and scored and cannot be cleaned up with crocus cloth replace the piston

  17. 4. Clean up caliber with wire brush, if time permits dry and glass bead.

  18. 5. Install rubber parts lube up with brake fluid

  19. 6. press piston into bore with C clamp or large water pump pliers

  20. Before you push the piston back into the cylinder take the cap off the master cylinder and drain out some of the fluid

  21. If you are just changing the pads and push the piston back into the caliper, if you have anti-lock brakes I recommend that you flush out and bleed the Brake fluid before you push the piston back in. I don’t like old fluid going back into the anti-lock components.

  22. If we allow the junk and debris to go back up to the anti-lock components we can have problems. Please advise customers to have the brake fluid flushed to get rid of the debris and moisture in the brake fluid.

  23. Clean with wire brush lightly grease all contact points between caliper and anchor plate

  24. Check all rubber guide pin bushings and o-ringscheck the anti rattle clips replace if worn or damaged

  25. reassembled bleed brakes

  26. Instead of rebuilding the calipers you can get a loaded caliper (ones with brake shoes in) by replacing a caliper instead of doing it yourself you get some of the liability off of you.

  27. The End
