Outter Brake pad not fit

kkyin · Post by **kkyin** » May 21st, 2005, 7:53 pm

Trying the change the front pads, i pushed the piston all the way back, but there is still not enough room to put the outter pad in.
The inner pad fit well. Any help would be appreciated.
I have a 93 GS disc brake all around.

Your caliper has seized.

YOU THINK lol. Bud you have not pushed the caliper all the way in...cause if it was, the pads would fit. But yah, by the sounds of it you need to either rebuild the caliper yourself or buy a new one.

How do you push a caliper in? please explain....... Your piston is fine, the sliding bushings on the caliper have siezed, pound them out clean em up and use silcone lubricant, and make sure the boots aren't wrecked. Or you can just buy a new rebuilt caliper if it's to far gone.

the bushing is the metal tube thing that the caliper bolt goes through, right?

Thanks.
Now i have problem removing the rear pads.
How do you take the caliper off so there is enough room to put the pads in?
Looking at the manual, it seems like you can just untighten one bolt to remove take the caliper off. Is that right?
And, do i use the clamp to push the piston back?

thank you again.

Remove the upper bolt, and then pivot the caliper. You should now be able to slide the caliper out if the caliper isn't seized.

I used a 17mm wrench to push the piston back in. You have to push and turn clockvise.
Good luck!

I can slide the caliper partially out, but the brake line is limiting how far it can pivot out (not enough to put the pad in). How do I get more room with that?

Loosen the clip that holds the brake line. If that dosen't give you enough roomt, remove the e-brake cable.

for the rear brake piston, do I need the special tool to twist it back in?
or I can just use a clamp to push it back?
Thanks

No special tools needed, just use needle nose pliers and turn it back in, it has 2 triangular grooves in the face of the piston - it's super easy. And when you put the new pad on make sure if it has a little stud on the back of the pad that it goes into the groove.

Also make sure to put lube on the sliders. You can buy it at your local auto parts store it is meant for brakes.

reminds me of I have this friend that....

hehe it wont go in unless you twist (or break it), and it doesnt take much force to put it in either with some needlenose plyers.

I almost always have to file down the metal backing plate of my new brakepads when I install them. The way they cast the mold is so crappy on most pads that there is a lot of flash remaining that sticks out and prevents the pads from sliding in easily.

My rear ones particularly needed to be shaved a good bit before they went onto the bracket.
