1st gen brake slightly sticking.

[master hec0]

on my 87 b2 it appears that the passenger front brake is sticking. just a little bit but its quite annoying because it causes a high pitched noise. what could be the problem? or what should i check 1st?

seized caliper....cheap and easy to replace,should do both.

 

[master hec0]

thats the only thing is could possibly be? is there not rebuild kits for these? last time i checked im pretty sure they were quite expensive.

 

[gwaii]

rebuild kits are a pain....new calipers should be about $50 each,and they come with new slider pins too.

i found them at Canadian tire they were quite cheap 43$ each roughly. and i get a 15$ back on each core returned. thanks for the help gwaii.

I usually replace the soft line with a stuck caliper.

It's probably pretty rotted for one thing if it's so old that the caliper is sticking,
and the soft line itself could be the issue (acting like a check valve).

But the new calipers may do the trick, just thought I would throw that out there.

DO IT. I about smoked my truck last year. It's a common problem for the calipers to freeze up. Make sure and lube the slide pins. buy new calipers.

i just had the same problem on my gmc i had to change both calipers, hoses, pads, got the rotors turned. and since i had it all apart i changed the front wheel bearings and seals

if it's just the caliper, consider yourself lucky. mine had a crack all the way through the rotor disc. i feel lucky that it hadn't seized or broken completely and caused me to crash before i found it.

the pads,rotors and bearings are all new. with less than 500 miles on them. the hoses are in good condition with no leaks or bulges so im going to leave them. I ran out of daylight so i will finish tomorrow man are those caliper pins a pain in the ass to get out last time when i took them out i didn't grease them this time im going to grease them.

for the caliper pins i found that a 3/8 drive extension is exactly the right size to use as a drift to push them out.tap the outside end of the pin with a hammer to set the pin in flush,then use the extension to drive them out.then a little grease on the new ones will help.not too much though,you don't want it going onto the rotors.

 

[master hec0]

i used the head of a roofing nail. it was the exact size. what kind of grease should i be using? the manual calls it caliper pin grease but shouldnt white grease do the trick?

 

[robertc1024]

I just used some high temp molybdenum sulfide wheel bearing grease on mine. The pins have little barbs on them to hold them in place on the caliper. If you can get a pair of thin-nosed pliers on the ends and squeeze them together a little bit, it makes knocking them out a lot easier. Might need another hand though!

 

[master hec0]

i got them in and out on my own. i just got some multipurpose grease. now to bleed the brakes. this will be a learning experience
