freeing up stuck caliper slide pins

[carpman15]

i did the brakes on my front axle the other day and i found a few of the caliper slide pins are froze up im sure people have run into this before - i tried light heat - all i had was propane torch- i tried penitrating oil and vibrating with air hammer that didnt work either so being out of time i put it all back together but i know the pads wont wear correctly so i will need to pull it back apart

also i will be doing rear brakes on it soon is there any tips for dealing with the park brake shoes etc ?? i havent done disk with drum park brakes before - also if it is important it is early 99

thanks everyone

go buy new brackets and slide pins from an autoparts store they are not that expensive.


Advanced Auto, new brackets all the way around $50
new slide pins $16 per axle
slide pin boots $13 per axle

I spent hours fighting with one bracket/slide pin and lost. cheaper to replace those parts than to replace pads and rotors when they wear out, not to mention how much of a fuel hit you will take from dragging a brake pad.

that was my other thought just kinda figured theyd be a little pricey

I just did mine recently, only 1 on the whole truck was seized but wow...
I tried with oil and propane heat, no dice. I had to break out the oxy acetylene torch and heat it to a dull cherry, then it SQUEAKED it's way out. I cleaned out the bore with steel wool on a drill bit and replaced the pins. No pull on the wheel when I jam on the brakes, nice and free floating.
I wish I would have known they were so cheap new... If I didn't have the oxy acetylene torch, I would most def go buy the brackets.

Enjoy!

I did one where the pin was SO stuck. NOTHING worked. It was a Sunday night and all I had was an extra pin, not an extra braket. I drilled a hole on the back side of the bracket and pushed the pin out that way.

That was the only solution.

I used the same type of torch and it worked like a charm. When I asked at the auto parts store they said they did not sell just the bracket and I wasn't about to replace the caliper for nothing. I checked advanced, napa and carquest for the bracket.

pb blaster and heat works wonders

Depends how stuck. Some cases blaster and heat will not work. The 03 I did I had it red hot blaster smoking in a vice with a pipe wrench. Nothing!
