help...rear brake piston doesn't go back in

Post by **s14mc** » Thu Jul 31, 2003 3:49 am

so i was changing my rear pads and couldn't press the piston back in after installing new pads. i ended up disconnected the brake line and unscrew the bleeder and it still doesnt move at all no matter how hard i press it.

please help.thanks.

You need the lock that goes at the end of the piston to turn it back in. I think you can get one at Autozone.

you dont need a lock, the piston should have a big cross in it, you can use a huge screwdriver, or something else to turn the piston counterclockwise and push it back into the caliper.

On my S14 it doesn't have a cross. It only has the four "cuts" on the outer parts of the piston. So a screwdriver didn't work. The only thing that did work was that lock tool. I even tried a vice and turning the piston/caliper but that didn't work either.

its hard as hell, but I just did mine... you have to use a set of needle nose plyers to do it with. You will curse the living hell out of em, but it can be done with plyers.... make sure to adjust your parking brake when done as well.... mine was tight enough to drag my pads and make them smoke

open up the break fluid reservoir and that should take some pressure off thus letting you screw that mothafuzz all the way in.

Yeah you can use needle nose pliers or even some vise grips to grip the piston and turn it counterclockwise. Just be careful not to rip the rubber boot that wraps around it.

a rear brake piston tool is like $5 at sears, autozone, advance, pepboys,etc. just get the right tool. if you have to do it right now, then use vice grips. they make it easier than pliers.

counterclockwise??? i thought you have to turn it clockwise...to push the piston back in...some1 confirm that?

i think i turned mine clockwise to go in, its been a whilebe careful with the needle nose pliers, i kinda tore up the piston face every time the pliers slipped before finding that tool from autozonebest bet is go to autozone

Yup, the tool is like 5 bucks at AutoZone or Napa. And yes, you turn it clockwise to push them back in.

Make sure you crack open the bleeder screw or take the cap off the master cylinder reservoir when you push it back in.
