Torque specs

Hi guys,

I'm doing my brakes today, and can't seem to find in the shop manual where the torque specs are. Maybe I'm blind, but I thought I looked through the entire BR section, and all I can find is "tighten to the specified torque setting". Which is where?
In another one of the many PDFs?

Thanks,

B

They are typically on the exploded diagrams in the FSM.

Right you are. I didn't look close enough. 85 and 43 ft lbs for rear mounting bolts and slider pins respectively.

I finished the job this afternoon, not too bad with the right tools. The rear caliper lower mounting bolt was a bit of a pain, being behind the arm where i couldnt get with the gun.
I have 2 questions about the job, as it's been a couple of years since I last did brakes.
After the initial bed in of the pads, I decided to go through an alley with the windows down to listen for and problems. I noticed the pads sound as if they are dragging on the rotors slightly. I say slightly because I only notice it in the alley, and it is not that loud. Is this normal for a while until everything sets in? How do i know if the bedding in process was successful?
I know this next question has been asked before, but depending on where you go, I've seen different answers. Front and rear pins have a plastic or rubber bushing near the end of only one pin per caliper. I didn't notice it until I was cleaning and re-greasing them. What is this for, and does it go to the leading or trailing side of the caliper. What will I notice if they're in the wrong spot?

Cheers,

b

And thanks again Black Betty for the Power Stop recommendation. Here it is complete:

Not quite the right torque...

For those who may see this in the future, these values are actually specified in the Factory Service Manual (FSM) as follows:

84.3 (8.6, 62)
43.15 (4.4, 32)

That is:
84.3 N-m (8.6 kg-m, 62 ft-lb)
43.15 N-m (4.4 kg-m, 32 ft-lb)

Units matter!

Amen. I go over the ft-lb values with a highlighter to avoid this sort of mistake.

I snapped the bolt that goes inside the caliper cylinder last year while replacing pads, I was lucky to spin the broken part inside the little cylinder and get it out.

Guy at autozone matched the replacement from another car which fit perfectly.

What a Sunday that was..
