Shaking while braking even with new Front Rotors

[Boaring1961]

I need to get the torque specs for the rear caliper and caliper bracket. Is there a web resource that has a list of the torque specs for this and maybe all the bolts on our trucks?

Caliper pins are 24 ft*lb.
Caliper adapter mounting screws are 130 ft*lb. Although frankly I think that's a little excessive.

Thanks Ryan.

Another couple of questions:

Should I keep the old front pads that come off my truck? They have 75% left. Could they be reused on a new set of rotors?

I just did the front brakes a month ago (new rotors and pads) can I still replace the calipers now or is it best to do the calipers when everything was done?

With new rotors I would do new pads. Not that you can't reuse the old ones but I think matching new to new will give you better perfromance. While the old pads may 75% left they could have a surface that may not work as well with a new rotor.

You can replace calipers at any time irregardless of when you di the brakes.

This may have been caused by tubing or clamps that are loose. Or left hanging callipers from towing as suggested above.

Just finished replacing the rear rotors, new calipers and pads. Not an ounce of shaking or shimmying going on when I apply the brakes coming to a stop. Thanks to those that contributed with help and information.

I did the work myself and I'm very happy I didn't have to pay the stealership $300 in labor to do it. Since I saved so much money on this job I was able to justify for this job buying a Precision Instruments 1/2 In Dr Split Beam Click Type Torque Wrench. It'll come in handy for future jobs too.

I hope you broke the pads in, In the correct manor

 

[Boaring1961]

mfurrh55,

Can you elaborate on what the correct break in is? I've been doing it my way for a long time and have never had a problem, but I'm wondering if I'm doing something wrong or should be doing something else.

Thanks

just a series of hard braking at about 30 mph down to about 10 mph, without letting your brakes cool down and then driving it a little while and letting them cool slowly, close enough, when you replace rotors some manufactures will give you directions how to break in your rotors, Monte

 

[Boaring1961]

That's not too far off from what I did and have been doing. Thanks Monte.

check if your exhaust system has got lose. Tighten the clamps and if it is welded you will have to weld it back in place.

If the exhaust is too damaged, consider a whole exhaust kit to replace the one that you have
