Service Help - Seized Rear Calipers on '99 4WD
Greetings,
This started off simple enough with grinding brakes in the rear. I figured worn pads and rotors, so I quoted the parts from Rockauto to replace the front and rear setup. I found a Firestone coupon to replace the pads and re-finish the rotors for the same price as the new parts. Since I work 12 hours a day, I figured I would let the shop save me the headache.
Well we took it in to Firestone today and the rear calipers are seized up and the parking brake shoes are shot. What grabbed my eye as funny was a $216 service charge to remove and replace both rear axle shafts.
I've owned a 2nd gen S10 Blazer, and a 1st gen S10, performed brake jobs on both, and never came across that in the procedure. What do you guys think, total BS?
Thanks for your time.

Axle shafts do NOT need to be removed to service the rear brakes. They do need to be removed to replace the axle shaft seals.
Each time the brakes are serviced, (pads & rotors) the calipers & brackets should be replaced. If not, you WILL have problems. The pistons are steel and the caliper is aluminum, corrosion will cause the pistons to bind in the caliper bore. The brackets are cast iron and the guide pins are steel, corrosion will cause the pins to seize in the brackets.

Simple job with common hand tools, less than an hour per side. Your 1999 has ABS brakes which can make bleeding a challenge if not done correctly. When removing the old caliper, have the replacement ready to install so there is minimal fluid leakage during the swap. After caliper replacement, gravity bleed, (do not pump the pedal) each caliper separately, before final bleed, and make sure the master cylinder never runs dry of fluid.

Why gravity bleed as opposed to speed bleeding?

Must be a second gen thing, cause I just had to do the calipers on the first gen, only because the seal around the piston started leaking.
I am still getting annoying sticky brakes when first driving in the morning while its raining, quite annoying, could be me getting ****ty pads LOL
