Re: 1999 Silverado 4x4 front caliper bolts stuck

I'd not use an oxy acetylene torch on them. Get a MAP gas or butane torch and heat them up till you don't want to touch them bare handed. Try to heat one and not the other.

However I think Spidey is the SME on this and if he says you don't have to remove them then don't.

for those who don't work for the gummint in a hoity-toity white collar office, SME means Subject Matter Expert.

(damn I wanted to be an SME when I worked for Uncle...never quite made it.....)

I've used an oxy-acet torch to warm them,
I'd recommend replacing all the rubber hardware anyway.

Clean and lube the caliper slides before reassembly.

You know I will.... ;D

Remember the good'ol days when you could chuck the Vise Grips down on the bolt shaft and get'em out that way?

LOL...don't think for one moment that would've been beyond me if it was possible on this truck(woulda had to replaced them for sure, but hey..).

Waiting on the "better half' to get her ass home so I can run up to SJ's shop to do this.....next house WILL have a damn garage(never buy another one without it again)

you know the oem use some really nasty thread locker on some of there stuff and it takes heat to get it to come apart new or old . ever take a front leaf spring bolt out of a ford super duty ?a good I/R impact wont touch them with out HEAT

Re: 1999 Silverado 4x4 front caliper bolts stuck

Well, got that taken care of.....

TC, I doubted you....glad I was wrong.

Those caliper bolts wouldn't budge for ANYTHING....the bracket bolts broke loose with my old Craftsman 1/2" drive breaker bar and an 18mm socket(Thanks for the heads-up, Spidey).

Damn good thing they did...was a pain in the ass doing it that way(ask SpeedJunkee, he helped), but got it done.

Healthy amounts of slider lube was used, lack of it was what caused the left side to bind and wear the inner pad to the backing plate....never squealed or anything, it just went to the metal.

Looking at everything, I can't believe how far the brakes and suspension has come along since the 1973-1987 run....dual-piston calipers, big-ass rotors...hell, the damn thing has better brakes than my '85 Z28!
