Replaced wheel stud.. got a question.. (1 Viewer)

[gbell210]

Well I replaced the single broken rear wheel stud. Only took about an hour and a half for my first time doing something like this. Ran into 1 questionable problem. WHen I went to remove the caliper I first looseed the wrong bolts. I started to remove the bolts in the picture below:

I realized once I was able to see about a 1/2 inch of thread that these weren't the correct ones, so I tightened them back down. This is my first time working with disc brakes (have done drum several times before) so the question is... What do these bolts do, and did I harm anything by loosening and then re-tightening them??
Thanks,
Gary

Call me crazy, but I just pound out the wheel studs out the back of the rotor, then place the new one in and tighten the lug nut onto it without the wheel until it seats properly, then put the wheel back on.

Don't know if what you did will cause any problems, but I can't imagine it would.

Rookie2 and I did the same thing on our axle job. The two correct bolts are a little farther back and down on the caliper and parallel below the caliper...I'll post pics when i get back to Ohio.

Since I was pulling the pads off the back, it wokred fine to pull the two screws you mention above. It basically allowed me to pop the pads right out without any worries. The two screws allow you to access the pistons on the rear caliper, while the pads are attached to the other part of the caliper on the rotor.

Just torque them up to specs. and you'll be fine...at least now you know how to get to your caliper pistons...

V-DAWG:
I thought I was going to be able to do that as well, but turns out the dust/brake sheild completely covers the rear disc. I didn't see any holes in it to get at the wheel studs. Unless there is a secret hole or a trick to it that I didn't catch reading up on old posts.

Thanks Onur, but I did find the correct 2 bolts, and the caliper came off fairly easy after that. Banging the stud out was the toughest part, luckily I had some PB Blaster which I think helped, after beating it to death.

Just a comment. If you are replacing a stud. Do all 6. In all likelyhood what was done to compromise the one was done to all of them.

i second that notion. the costs isn't in the parts, so do 'em all while you're there.

when the next one breaks on that wheel you're going to kick yourself.

Why are you guys working on these trucks without proper documentation? Are your lives and those of your families not worth having proper assembly and disassembly methods and specs? You buy a $40,000 truck and won't buy a $100 book about how to work on it?

p.s. Those pins are the guide pins that the caliper slides on. Did you tighten it back down properly?

We had two FSM's there and still pulled the wrong bolts...

I'd imagine this is a common mistake. Presentation wise, these two bolts are very similar in look and location to the two bolts that hold on the front calipers. The bolts that hold on the rears are recessed and somewhat hidden behind those bolts, so it's hard to see them unless you stick your head up in the wheel well and behind the disc.

Don't get me wrong, I wasn't too proud of myself on that one.
