Good morning all,
Wondering if someone could help me out. I’m currently doing a brake job on a 2017 dodge Durango rt v8 hemi. I have the Haynes manual but it doesn’t really talk about the specks for caliper mounting bolts and bracket mounting bolts. Also, they say not to lubricate the sliders which I find weird.
I’ve never used a torque spec in the over fifty years i did brake jobs.
I just tightened the bolts as much i could with a socket and a half inch ratchet.
I always lubricate the sliders with brake caliper grease.

Typically caliper to bracket bolts are small and are torqued to around 30 lb-fts, or a good and tight with a wrench or 3/8" drive short rachet NOT a 1/2" drive much longer handle rachet as tight as you can, cause you will over torque it and snap the small bolt…
However, the caliper bracket to spindle/knuckle mounting bolts differ a lot from manufacture to manufacture and size of vehicles and front to rear…
It looks like your caliper front brackets torque to 148 ft/lbs and rears about 100 ft/lbs…
caliper slide pin bolts are 41 ft/lbs just fyi
Lube as needed/required…
Caliper bracket bolt is a M14-1.50
Caliper slide pin thread is a M9-1.25
Tight as I can? Ya think you could strip a 1/2” bolt with a breaker bar? I could
Thank you so much. Greatly appreciated!
Who said anything about a breaker bar?

50 years of brake jobs using a 1/2" ratchet and tightening them as much as you could? On the caliper bolts or the caliper mounting bracket bolts?
I also find the thing about not lubing the sliders to be weird. Presumably, they are encased in rubber boots that protect them from the elements? If not, I would find that weird too, but would reluctant to coat them in a dirt collecting substance…
As for the torque specs, Haynes can’t always be trusted, but they put the torque specs at the front of the Chapter. So did you look there?
And the advice re: the bracket bolts vs caliper mounts is correct. The brackets are generally over 100 ftlb (I have a GMC Envoy where the fronts are 150), while the caliper mounts are way down low. More like 20-30 ftlb or even less (especially in the rear).
Here’s a thread where someone posted specs for a 2015 - probably the same as for 2017, but it also didn’t say where the specs came from. So I’d double check it: Front & Rear Caliper Bolt Torque Specs Needed | Dodge Durango Forum
Thank you so much. They are in a rubber boot, I’ve just never seen any manual day don’t lube the pins. I did look and they do give the specs but I don’t believe it’s accurate for a v8 hemi with heavy duty brakes.
Some applications call for lubricant on the pad-to-caliper slide surfaces, most do not. If you live in a high corrosion area, you may choose to apply lubricant where the brake pads contact the caliper brackets.
Caliper guide pins should have lubricant.
Yeah. Good to be skeptical of Haynes. The Haynes I have for my Envoy (came with it when I bought it used) gave me 80 ftlb on the caliper bolts - ugh. It’s supposed to be - I forget - only 25 or 30 ftlb. 80 is stripping/breaking territory.
Good point. In the initial post you just referred to “sliders” - which I took to be the guide pins/caliper mounting bolts. (The ones inside of the rubber boots that allow the caliper to move). If we’re talking about the “ears” on the pads where they contact the shims/retaining clips on the caliper (the guides where the pads ride), then often those shouldn’t get lubed.
