About to wrap up an RXT clutch replacement after the car has been down for about 10 months. All my parts were bagged, but I think I somehow mixed some things up.
In the bag for the handbrake line bracket bolts, I took out these bolts. They seem to be far too long and slightly smaller diameter than what I actually need. I can't even get the bottom one in due to shock clearance.
So, I need some help from you folks. I can't find any other bolts that will fit in the bracket. Does anyone know the dimensions/specs of these bolts so I can find a replacement locally?
Or, where can I order them?
Anyone know where the heck those bolts may actually go?
Those look correct to me. They are deceptively long bolts for such a small bracket.
They absolutely don't seem to fit. They seem too narrow, don't engage the threads, and are pushing the rotor away from the hub if I push hard enough (Could be the parking brake assembly pushing the hub?). Also, I can't seem to even get the bottom bolt to clear the shock if they are the correct bolts. Can you, or anyone else confirm this?
Here is one of the bolts trying to clear the axle boot and shock for the lower mounting hole. It hits either one from both sides/angles.
I'm in no way saying you are wrong. If they are correct, I can't get them to thread into the top hole, they seem too long, and won't go in the bottom one at all.
Can we verify they are correct? The bolts are 3" long with a 3/8" diameter shaft.

Those 4 bolts are supposed to be M10X1.5X70:
Item #6
Note: be cautious when looking at the proportions of things in these drawings. They are NOT always to exact scale and can be deceiving sometimes. Always go by the written description.
The official description is: "BOLT RR BRK,HFH,REDUCED BODY,M10X1.5X70,30THD,22.3 O.D.,9.8,7114M,(PARK BRK ASM MTG),(M10X1.5X70,9.8)"
It seems these bolts are a "reduced diameter body" (which yours appear to be), with a 22.3 mm diameter head and are Grade 9.8 (a metric hardness grade), and they SHOULD be 70 mm long (measured from under the head to the tip).
Edit: The GM part number for the correct bolts is/are: 11516356

those look right as far as I can remember... I'm pretty sure I got them threaded in most of the way before I put the shock in that way I had room to get to them

I'll play with it tomorrow a bit. I unbolted the shock from the top when I removed the cradle (don't remember if I did parking brake before or after shock). I'll unbolt it again tomorrow if necessary to see if that'll give me the clearance I need for the bottom bolt. As for the top...it goes in quite a ways but doesn't seem to want to thread. Felt like it was a couple of times, but it came to a hard stop with a lot of thread left (worried about cross-threading).

My thoughts exactly. Maybe a dab of anti-seize on the threads might help a little.

I always start threads by hand, I cringe when I see guys use air/cordless tools to start bolts... someone with experience can do it successfully 99% of the time but the other 1% can be a real bitch!
I never bothered pulling the rotors off to look but I suspect those bolts attach the E-brake mechanism to the spindle. I know the part they bolted into was loose inside the rotor but they started fine so I never bothered pulling the rotors to look at it closer.
Maybe you pulled them after removing the bolts on the upper a-arm which allows the spindle to be pulled-out??

i was under the impression that what they screw into something that can move inside the drum if you take them both out at the same time so i never have. I didnt think they threaded into the knuckle but some part of the brake assembley under the rotor so you might have to pull the rotor to square it up to get them back on? Possibly they hold the adjuster down?
I just pop the toelink or the upper control arm to get them out, the shock is like 150 ftlbs or something silly.
Removed the upper control arm bolts and that gave me enough room to move the suspension assembly around and get clearance for the bottom parking brake bracket bolt. After working with them a bit, I was able to bolt them up just fine. Wrapping up the 10 month long project TOMORROW. Beyond excited.
