How To Remove Old Calipers And Install New Ones Properly?? - 2003-04 Mach 1 Registry Owners Club

I'm replacing my (FRONT) calipers for the first time myself, and i'm not sure how to do it properly. Do i just disconnect the brake line from the caliper and install the new caliper quickly to avoid losing fluid and collecting air in the brake line. And will i need to bleed the brake line afterwards??

Does it need calipers or just pads? If it needs calipers you will absolutely need to bleed them before driving it. If pads are all it needs you can do them without bleeding.

Id make sure youre ready to swap the line from caliper to caliper as quick as possible, I would also have the lid off the brake res and a bottle of fluid nearby. Whatever you do, do NOT let the master cylinder go dry or youll be bleeding it too.

Personally, I would bleed the brakes at all 4 corners to be on the safe side, probably a good idea to flush the system out anyway.

I love speed bleeders, I know they sell them at autoparts stores, 12-15 bucks per set of 2 (front rear are different part numbers I think). They have a one way check valve, that fluid/air can go out but it cant come back in, you just leave it cracked the entire time youre bleeding that caliper and close it when done

One other question, how do i tighten the dust shield?? Its loose and the rattling drive me insane.

i think there were just two bolts on it, I wanna say you can see em/get to em with the rotors off

The front brake shield is riveted on not bolted, guess i can grind it off and have new ones put on
