I've recently purched an 86 rx-7 and it has the 4 piston brakes on the front. on the passenger front caliper, 1 of the pistons is seized. the other 3 go in fine. I can't get the brake line off the caliper to try compressing the piston a little easier. any suggestions on either?!?

 

why can't you get the brake line off?

sounds like it needs a rebuild pretty badly

 

the nut is pretty rounded off. i'm going to try a little bit of heat from a propane torch and maybe some vice grips.

 

file down the nut so it has two parallel flat sides and then use a channel lock

 

ah, i'll give that a try as well. thanks!

 

Okay, got teh caliper off, but the piston is still frozen.

also, i can't get the rotors off. I took the set screws out, but beyond that, i have no ideas why those damn things won't come off!!!
