rear brake problem

ninjajim4 · Post by **ninjajim4** » March 8th, 2005, 6:46 pm

hey gang,

the other day i noticed a grinding sound from the left rear, so i took a quick peek at the wheel. i noticed that the rotor was rusty as though the brake pad hadn't touched it! i took off the wheel and found that the outside pad wa pretty much untouched, but the inside pad was completely worn away, and some nice grooves cut into my rotor

i changed my brake pads maybe 3 wks ago or so, and i would guess that all this time the inner pad has been in constant contact with the rotor, while the outter one hasn't been doing anything.

can someone tell me what i did wrong and how to fix this problem??

this is for non ABS, disc brakes.

thanks guys

the rear guild pins are siezed, or ur parking brake is sticking, so it's not releasing

i'm pretty sure its not the parking brake. what about these pins tho? what causes those pins to seize, and how do i free them up and prevent htis from happening again? thanks

u can tell is ur parking brake is siezed on the caliper, by looking at the return spring, if it is all the way back againt the mteal tab, then it is released, u might need to adjust it
take the pins out, and put them on the wire wheel, and clean up the rust, and use lube on them.
u might need a air hammer to remove the pins, cause they get really siezed up

Is it possible that he is having this problem because he could of screwed something up while changeing his brakes 3 weeks ago?

yea thats what i was wondering

ive changed brakes before on other cars, and this didnt seem to be anything different, but still... seems a lil coincidental

i hate to sound like a complete dope, but oh well

someone put up a pic of calipers here:

http://www.mx-3.com/phpbb2/viewtopic.php?t=39000

are the guide pins the two pins on either side of the main piston? do i need to worry abotu those pistons that are covered in the rubber? Can i take the pins off without removing the entire caliper? and am i best off just getting a new caliper altogether?

thanks for helping this newb out

those pics are of front calipers.
rear calipers don't have those 2 tiny pins
get some rebuild calipers, it's alot easier

Here in Barrie, Ontario you can get a front caliper for $60.00cdn + tax. The rear caliper is about $130.00cdn + tax.

Im' confused on how you don't know what a front caliper and rear caliper looks like....but you did your own brake job 3 weeks ago.

i knew the one from the picture was a front one, though ive never changed my fronts, so i actually have never seen a real one up close. but yea.. dont look all that diffrent to me. am i supposed to photographically recall what the rears ones look like?
