Hey guys,

Today I had a fun day installing the Baer/Eradispeed two piece cross drilled/ slotted rotors on my dad's C5.

Didn't quite go as smoothly as I had hoped. One of the rear drum/e-brakes was seized up and the original rotor wouldn't come off. Ended up getting it off, original ebrake shoes were cracked. I think it is because he barely drives the car. It's a 2001 with only 30,000kms on it. Looks brand new, wheel wells don't even have dust on them

Anyways, the point of this post is because once the rotors were installed, and wheels were back on the ground, there was a slight squeeling/grinding noise when the wheels were rotating. It was coming from one of the rear rotors (The + sized rotors with the brackets that move the calipers out). When I was installing them, I noticed that when I bolted the rear caliper on, the rotor barely had clearance within the caliper (it would contact the metal caliper body not the pad).

I'm assuming the caliper brackets can work on either side as there are no markings on them, and they are symetrical. So I figure those were installed correctly. I also feel that the pads still have quite a bit of life on them, he only has 30,000kms on the car and he drives it like a grand pa but doesn't ride the brakes. I'm wondering why there would be an issue with contact, and I was wondering if anybody else has had this problem?

I may get in touch with baer and see what they have to say. I don't think the grinding/squeeling is normal even if they are new. I suppose I could add a washer in between the bracket and the knuckle to space it back slightly further, but I don't want a band aid fix after paying quite a bit for these rotors.

Any suggestions would be great. Thanks guys!

 

By the way, here are some pictures of the brake upgrade and new wheels.

 

You sure that you have a flat washer between the hex head bolt and the new intermediate bracket? If not the bolt may be rubbing on the inner side of the rotor?
Once getting under the car You will be able to tell if it's rubbing there, because you will be able to see the inner sides of the rotors scratched/rubbed..

 

Yep, made sure the bolts and washers are all proper. I'm 99% sure the rubbing is the rotor against the caliper body. I'll see if I can snap a picture tomorrow

 

You need to pull those wheels off and reinspect everything. Once thw wheels are off lay some painters tape on the outer edge of the rotor and see when you spin the rotor if it scuffs the tape. The other bolt that uses an allen wrench , the head should be on the inboard side & the flat washer and elastic stop nut should be towards the outside of the car. That elastic stop nut should be thin like actually an elastic stop "JAM " nut. Are those after maket calipers?

 

I have the bolts in the right way just as you described. The driver side is perfectly fine. Not sure why the passenger side is giving me this issue.

I'll take it apart again tomorrow. What a P.I.T.A.

 

If it is rubbing in the place you decribed, because there isn't much space in between the inside of the caliper & the o/s of the rotor. You could probably get by w/ taking the caliper off & using adisc grinder in the area that it is rubbing. I really can't see why it would be rubbing in that area, unless those were aft market calipers, or one rotor is over sized. I think once you pull the wheels back off you will find the problem. Good luck and let us know what you find.

 

Here is where it is rubbing:







As you can see they are the stock calipers, and the rotor is stock thickness. How can I get the caliper to move back slightly? I don't want to space the spacer with washers. I shouldn't have to do that if the driver side was fine. I know the calipers slide.. I might try adjusting the pins? I'm at a loss here for why it would be like this.

 

Looks to be installed correctly. The stock rotors thickness must have been less than the Baers? I'm assuming both Baer relocting brackets are of equal thickness? I wouldn't put washers/spacers to make things allign. Try giving Baer a call in the am. I've never heard of any one having that patticular problem. I have a 03 Z with the same Baers as you rs. No problems. I think it falls back to that caliper.

 

I ended up using a washer as a spacer between the bracket and the knuckle. Spaced it out perfectly. Took it for a short drive, no issues.

Although I don't like the idea of it, it should work until I get a hold of baer. Either there is a problem with the caliper or the bracket or the rotor. I didn't have time to take the other side off to inspect it and compare, but who knows.

 

I had the same problem with some Baer brakes on a 62 Impala it needed shims also. Bill, and Rick one of the tech guys went out of his way to help, great bunch of people. This is his email rickp@baer.com

 

I bet the top part of the caliper is where you are having the rubbing issue,try loosening the 2 allen bolts that attatch the adapter,keep the caliper intact,once you loosen the allen bolts,place a flat head screwdriver between the top part of the caliper and the finned edge of the rotor and pry the caliper outward,you will be surprised the minimal movement will make a difference being there isnt much clearance to begin with,while you have tension on it,tighten the allen bolts,see if that helps,let me know,thanks and good luck!

 

Thanks for the suggestions guys. It wasn't the top part of the caliper that was rubbing, it was the inboard side of the caliper mount, not the body that floats. Because the contact was in the "side to side" direction with respect to the car, loosening the allen bolts wouldn't help. The only way I could get clearance is with those washers. I have no clue why it would be fine on one side, and the other doesn't clear.

 

Guys,
Does anyone know if the two piece, Baer Eradispeed set up will fit a base '99 coupe with factory N73 Magnesium wheels, and C5 Z06 calipers?

I am concerned about clearance, especially on the rears.
thanks!

From this picture it looks as if the Baer Bracket off set in wrong. The bracket is to move the caliper bracket way from the center axis, not closer to the back of the rotor. Look at the original bracket mounting surface. Now look where it is now, Up & In. Check the other side to see if the offset is the same, I would not think so. You may have the wrong or miss made bracket. Either way Baer will get you fix up Quality Stuff!

 

Thanks guys,

The car is parked now for the winter, and I will have access to it again in the spring. I may take the brakes off to inspect everything again, however, from what I remember, the brackets are the same on both sides. They should be interchangable and symmetrical. Maybe I got a botched bracket on the one side, so I'll disassemble in the spring and look. Otherwise, I drove all summer with using hardened washers as spacers and I did not have any issues.

 

I have 19" rears, and the factory Z06 calipers still contacted the rear wheels. I just took off the calipers and ground them down about 1/8" at the spot, and repainted them with hi-temp rattle can. Three years later, they look as good as new.

 

FWIW,
Here are what my rears looked like I just took off & sold.

When I put my rotors on I had to get balance weights on my wheel repositioned cause they were rubbing.

 

N73 factory magnesium wheels?
