MRHYDE needs front brakes

Well those fancy two piece rotors didn't fit. They sure looked awesome. The rotor bolts were hitting the pad, and when we went to tighten the caliper bolts it was pulling the rotor too far in (yes the pistons were compressed) and not allowing the rotor to sit flush against the hub. A trip to autozone and $35 a rotor later we put ones on that fit. I'm sure we will be swapping those out to some nicer ones soon, but it got the car back on the road for now. We should have taken pictures.

That oil filter is kind of a pain to change too. Once we got the fender liner pulled back it wasn't too bad though.

Sorry to hear there were fitment issues. I do not recall Aric saying he had to modify the rotors or calipers to make them work. I will ask him the next time I see him. I am sure you noticed the rotors are directional, but not sure if that would cause them not to fit. I do know Aric spent some time making the ARP chromoly wheel studs fit on the Cobra hubs on my car, but that was it, and should not of made a difference. :frown:


Here's some pictures of my install:

They appeared to be bolted correctly. Mike must have had his Pads shaven down a bit to clear the bolts???? as they look extremely close in those pics. A one piece rotor should do the trick.

They were definitely close, if it was just the bolt heads I think we could have figured something out. We could have slightly modified the pad or even the edge of each bolt head (or both). The more concerning thing was the offset of the rotor that just didn't seem right. You could not get it to sit flat on the hub when you bolted the caliper in place. The auto zone rotors sat right in there perfectly. Something definitely wasn't right with those.

You must've been sent wrong rotors. Or the hats are not the correct ones.

Jeff, I've sent you a link to well priced DBA rotors.

I did see that, and decided to give them another try, they never warped or pulsed. And until the brake pad completely wore down they worked fine. Hopefully they will arrive in the next few days.

And Eric, in Mikes 3rd pic of the right side installed rotor you can see the threads of the yellow Stud are significantly less than the one closer to the caliper, so his rotor is torqued over as well. A mechanic friend of mine said that is normal, but the extra stress, and wear & tear (IMHO) is not ideal.

I don't know, I don't think that's normal, or if it is I wouldn't set foot in the car! :) The rotor couldn't sit flush even with the wheel pressing it in place. I've had some rotors where they are a little loose with the pistons all compressed and they don't sit flush until you put the wheel and lugs in place. As you know, the pistons were completely pressed in on yours. It was interfering with the caliper such a huge amount it there just didn't seem to be any way for the rotor and wheel to sit flush with the hub. Also, since the old pads were worn pretty evenly (inside and outside, not left to right) I don't think that interference was happening on the old rotors either. If the rotor was cocked over like that the pads would have been worn diagonally. It wasn't obvious to me which dimension wasn't right on the two piece units vs the cheap auto zone units, but by that time they fit and we weren't questioning it!

Did you check the thicknesses of the rotors? I still have them, when the new DBA ones come in (identical to what was on there before, and just shipped) i'll have to take a measurement. Another tool I should buy!

I don't remember if I checked the thickness or not. That could be it. Just pick up a set of calipers at harbor freight. That's where my cheepie pair came from, they have stayed more than accurate enough for the stuff I'm doing. If I was doing precision machining I may not use them.
