No, every manufacturer recommends you do this , I’ve had my calipers off my z06 at least 15+ times with the same bolts , never had an issue . When reinstalling just torque back to spec and you should be fine
It's probably good practice, but I've never known any shop that will replace the caliber bolts as a routine step. If you were doing your fourth or fifth caliber removal, then it might be good idea.
Have been wondering the same thing and interesting that I can not find one vid on youtube for 5th gen brake job. Surely someone with a 19 has had to replace pads or rotors?
Based on what I see here there probably aren't any over 50K yet. I'm at 45K and I still have a lot of pad left.
This is a CYA issue. Technically the bolts are going to get stretched a little bit every time you torque them down, but we are talking miniscule stuff here. Those bolts have to withstand a shear load and I would be shocked if the torque stretch compromises the shear strength anywhere near limits. In any case, I've done more brake jobs than I could even dream of counting and have never replaced a caliper bolt. As @Dusty1948 said above, if you were having the same caliper on and off many multiple times, you might think about it, but just in the course of common brake jobs? I wouldn't, I doubt virtually any brake place would, and I would be surprised if the dealer did either unless the bolts were 50 bucks each or they could add an hour of labor to do it.
Just did it today and reused the original bolts although put a dab of threadlocker on them. All else very similar to the videos you can see for 4th gen rams- however the clips are different- but pretty easy to figure out. My biggest problem was getting the rotor off. Also our 5gens have a rotor retainer screw that you have to remove which it seems the previous gen didnt have Got that off and the rotors were still rusted hard on! Ended up getting it off using a smaller diameter bolt going through the bolt hole that the caliper retainer normally uses. Washer and nut in between the knuckle and the rotor then turn it with the impact wrench.
oh those stupid retaining screws...just like Honda uses. The only purpose they serve is to aid in assembly on the factory line. Those suck sometimes to get off. I wind up grabbing a cutoff wheel usually. lol
How many miles on the brakes? Front or rears?
Yep, I usually end up drilling them suckers out then never putting any back in, no need for them
Its a '19 with 36,000 mi. Just did the fronts though. There was about 4mm of pad left but I was getting some ugly vibration under hard braking. Probably will hit the rears when I switch back to the all season tires in spring.
yeah.....no kidding! one came out easy. The other stripped very quickly and without even much force. Very cheap piece of hardware. I had to use the cutoff wheel as well to make a slot to turn with a flathead - still it was stuck. Then I took a 3/8 inch rachet extension, put it on the screw head and whacked it with a hammer a few times. Then came out no problem.Yep, I usually end up drilling them suckers out then never putting any back in, no need
Did you do the rotors too?
I've been around professional vehicle repair for sometime and I can't say I ever witnessed anyone replacing the caliper bolts at servicing. As far as that goes, I'm not remembering anyone using a torque wrench on them, other than me.
I was messing around in Uconnnect settings the other day and there is a setting for brake service that will "retract the parking breaks to all brake system service" perhaps this is an alternative to disconnecting the battery?
I think it is. The service manual instructs to use the technicians diagnostic tool, but I'm guessing it's the same thing in the Uconnect.
yes rotors as well.
