I changed my rear pads on my 91 Si yesterday and the inside pad on the passenger side was worn funny. Check this out.... Why would it do this?




TIA!!

 

Damn , was is seated properly ?

 

yea my guess, or the caliper bores could be shot?? im not sure, but what do the calipers/pistons look like? do they move easily??

 

uneven wear can be caused by bad calipers. its pushing more on one side more than the other, causing that to happen.

 

make sure ur slide pins are cleaned and lubed. sticking pins will cause uneven wear. they should be able to move freely in the caliper bridge

Thats the only reason on a Single piston caliper.

 

There are no slide pins that I know of on the rear calipers. Its just two bolts that hold the caliper together over teh pads. The piston turned in fine. Easier than the driver side piston did actually.

What do you mean were they seated properly? Are you talking about bedding them in or actually putting them in place on the caliper?

 

Where those 2 bolts go are the slides, The bolts screw into the slide. See if you can pull them out, the way the pad is worn im willing to bet one it frozen up pretty dam good.

 

make sure the piston is in the "+" position cause the nibble on the pad has to line up with the piston

 

Yeah this was caused because of the way the rear caliper is made its a screw in piston not a push in piston so the nipple on the pad must of not be seating right on the groove of the piston which was not mounted properly and was riding in an angle. Now when you did your pads did you screw the caliper in make sure you place the pads on the bracket the caliper should go in with a little play making sure that the caliper slides in with out having to be hammered the play will be filled out as soon as you bleed these.

 

yep, I turned the piston into the bore as far as it would go, then turned it out until it looked like this, "+". greased up the back of the pads, stuck them on the bracket, then slid the caliper over them. It went on with ease...no hammering. I can't remember what I did with these old pads...its been damn near two years...But if these get messed up also, they have a lifetime waranty, so I'll just buy a new caliper and replace the pads...Thanks for the insight guys!

 

buy a new god dam caliper and be done with it.

my pad looked the same.

If the caliper is still good, you spend about 20$ buying all new rear sliding pins and it won't do it again. Cheaper, and easier.

calm down gangsta. Money is an issue right now. So, no new caliper for at least a month.

I'll check out the slides on my next day off from work though.

The slot on the piston wasn't lined up with the pin on the back of the pad. Take a close look, you'll see where it was hitting.
