Hi everyone,

2003 Montana with a wicked shake in the steering wheel when the brakes are applied. It has been getting more and more annoying to the point that I finally broke down and bought new pads and rotors. But as I was removing the parts, noticed the extra set of bolts...the caliper bracket. WOW are they tight. Now I need to find a breaking bar to crack them. I have read on another post that the torque spec is around the 150 ft/lbs, can anyone confirm ?

What is the torque spec for the caliper bolts ?
What is the torque spec for the caliper bracket bolts?

TIA
Zig

caliper bolts go to 63 lb ft, the brackets are 137 lb ft.

My book is for a '99.

Good to see the actual torques Merc. Myself have never torqued to spec.

Bracket, 1/2 inch standard rachet as hard as I can go.

Caliper, 1/4 inch rachet as hard as it will go.

Always use a 6 pt socket.

I gotta say, I've never used the torque wrench for any brake parts either :eek7:

Many of the aluminum bolts are supposed to be replaced after removing them once. I've had the brackets off twice now and not replaced those.

I did put new frame bolts back in after I had the engine/tranny frame taken apart, maybe that makes up for my shortcuts? :shakehead

I got most of my mechanical wisdom from my Dad, who didn't even OWN a torque wrench. At least, I own one now, but I only use it for stuff like mating surfaces with a gasket involved or internal engine stuff.

When I bought my first Haynes Manual, I was shocked to see that there are torque specs for just about every bolt in a car.

Dad just said, "Tighten it up as tight as you can without stripping it out." I'm not a gorilla or anthing, so the advice has worked so far. :-)
