Brake Torque specs needed for 2008 Suburban

I have a 2008 2WD Suburban 1500 and am doing the rear brakes (disc). Single piston. The caliper bracket bolts, 18mm, are really tight. I saw a youtube tutorial that claimed about 130 ft. lbs. for these, but wanted to verify. Second, how about the 13mm caliper pin bolts? I thought I saw around 30 ft. lbs. but cannot verify. the caliper bolts are the ones where you need a 20mm open end wrench to keep the slider from spinning.

Any help greatly appreciated.

almost forgot - specs for 6-lug 17 inch wheels for same vehicle. I thought i saw 140 ft. lbs.?

Torque settings from Chilton's.

Install the brake caliper bracket mounting bolts and tighten to:
On 1500 series vehicles, 122 ft. lbs. (165 Nm).
On 2500 series vehicles, 148 ft. lbs. (200 Nm)


On 1500 series vehicles, use an open end wrench to hold the guide pins while tightening the guide pin bolts. Tighten the bolts to 28 ft. lbs. (38 Nm).
On 2500 series vehicles, install the brake caliper guide pin bolts and tighten to 80 ft. lbs. (108 Nm).

According to the chart, all Suburban models from 2008 wheel torque settings are 140 ft lbs

Are these same for front and rear? I got some info on the intranet that they were different?

You asked for the rear. I didn't look up the front.
Specs for the front are:

brake caliper guide pin bolts and tighten to:
1500 series: 74 ft. lbs. (100 Nm).
2500 series: 80 ft. lbs. (108 Nm).

Install the 2 brake caliper bracket mounting bolts and tighten to:
1500 series vehicles: 148 ft. lbs. (200 Nm).
2500 series vehicles: 221 ft. lbs. (300 Nm).

the caliper mounting frame bolts 18MM are indeed tough to remove. this is because there is a medium lock tight on these and when you re-install best you use the lock tight . to remove I use a hammer and a 18MM box wrench to loosen.. then on securing do the same then put torque wrench on to check for the torque.

on this you do not want is to have these fall out. I have seen some put anti sieze on these then they loosen , not good...

Thanks J cAT. So yes, they are hard to remove. I actually guessed on the torque spec, from another few 'experts' on youtube, and they mentioned 130ft.lbs., so I tightened the 18mm to that setting. A little tight, but probably ok. I did see some thread-lock on these bolts - yellow-ish compound. I did not put any additional on there - there was no guidance from either tutorials I saw or anywhere else. Should I take everything apart and do this?

I would re-check them that they did not loosen.... most importantly no lube on these . if you did use lube then I would remove clean and put some med lock tight on the threads...

if they are still tight then you should be good.
