my right front brake is draggin
when you jack it up so the wheel is in the air, you can barely turn the tire with your arms

theres a moanin sound when i drive like 5-15mph

is it the masta cyl
or the caliper

86 gxl

 

Caliper. When the master goes bad, it almost never causes the brakes to stick. The piston (s) in your caliper is probably rusted stuck. Get a rebuilt or new unit. Don't rebuild it yourself.

 

how much does a rebuilt caliper cost

 

mine were expensive.. i wanna say 75 plus a core.. but this is the heavy duty brake caliper (4 piston)

 

disassemble the brakes. check the caliper sides, try to push back the caliper piston, if it goes back, means its not stuck. obviously, next.. check the master cylinder. check for leaks. look for dirt around the resivior, brake lines, and next to the power booster. also, if the caliper is siezed, replace both calipers, do a brake flush, and brake bleed. might want to change your pads while your at it.

 

the fronts are cheap, like $40 with $60 core, at least mine were

 

I looked at the pads and the inner pad was totally GONE! The rotors alittle scarred but i THINK it will do alright. will a pad thats totally gone make the piston like push out farther than its sposed to and get stuck??
maybe??

 

As the piston doesn't recede after brake pressure relieved, it's holding the pad against the rotor, therefore causing the pads to wear. If you're not up to rebuilding the calipers yourself, just buy rebuilt units as stated above.

 

murrays discount auto sold me both single and 4 pistons for 29 dollars a piece + 50 core charge. not to bad.
