How to I fix rear brake caliper leak on a 2005 Chev Malibu Maxx

SOURCE: how do i replace the front caliper seal on 06

while the seals in the calipers are replaceable, its probably easier just to get a new/re manufactured caliper. if for any reason the seals don't work perfectly you could lose control of the vehicle when attempting to stop. with that said i'll try to explain the best i can how to replace the seals in the calipers for that vehicle.

1. jack up the front of the vehicle, place on jackstands and remove the front wheels, make sure the parking brake is on
2. unbolt the caliper and unbolt the brake line from the caliper and take caliper to a clean bench
3. remove the dust boot retaining ring on the caliper that holds the boot to the caliper itself
4. using a blowgun with a rubber tip apply low pressure compressed air where the brake line was bolted to the caliper to push the piston out of the bore (be carefull and ready because the piston may shoot out with some force)
5. when the piston comes out you will need to replace the dust boot and the seal so remove the boot and seal carefully so you don't scratch the piston ( the seal is actually in the caliper piston bore hole)and throw out the old seal and boot.
6. inspect all the surfaces and make sure there are no imperfections at all on the piston, the piston bore, or the caliper, if the surfaces are marred in anyway, replace the caliper, if they are good, using brake cleen and compressed air clean all parts then dry them
7. get the new seal and lubricate with DOT 3 brake fluid
8. install new seal into the caliper bore
9. apply a thin coat of DOT 3 brake fluid to the piston itself
10. install bottom half the the caliper piston into the caliper bore.
11. install new dust boot seal onto the piston
12. compress the piston to the bottom of the caliper bore
13. fully seat the dust boot seal into the caliper and install retaining ring
14. reinstall on vehicle (make sure to use a NEW copper washer on the brake line to caliper fitting) and bleed the braking system while checking for leaks.

repeat process for the other side.

if the caliper leaks at all from the piston after seal replacement, replace the caliper.

make sure you properly bleed the brakes before attempting to drive your car.

I didn't have a "cube tool", used a pair of channel locks. Worked great. Thanks.

SOURCE: how do i replace the rear brake shoes on my 2005

remove the tire, remove the brake drum. from there you can see the brake pads/shoes

SOURCE: I have a 2005 Chevy Malibu Maxx. It has a TC

i think it stands for traction control. most cars with that say ETC which stands for electronic traction control. if you have a manual for the car it should say what it is.

If you are replacing the rear pads and are trying to retract the caliper pistons here is what you need to do.
Use a piston installation tool in order to twist the brake caliper piston into the brake caliper bore.
If you do not have the tool you can retract the piston by using a needle nose plier.
Exert downward force and rotate clockwise until the piston bottoms out.
Before installing be sure the two "U" shaped slots are at 6:00 and 12:00 Oclock.
