Baer Brakes Issue

[4Motion4g63]

I just finished Installing a Set of Baer Brakes on my 91 AWD, and Backing out of the driveway for the first run, I Got 3/4 Of the way out and pulled back into the garage..

There Is a Terrible Grinding From the Rotor Dragging on the Lower control arm, at the edge where the ball joint mounts! Another problem is the rotor fits with allot of play around the hub? These brakes came off a 91 AWD used, Am I missing some shims? Do I just clearance the control arm enough to clear the rotor? How Do you center the rotor on the hub?

There Is ALMOST a 1/4 inch gap between the center hub and the inner edge of the rotor.

You need the centering rings, who ever sold you the kit probably forgot to send them or broke them - they're made very cheaply. Once you have the centering rings on, the rotor will sit snug and there wont be that gap. Because you don't have the rings, that's probably the reason why it's rubbing on your control arms as well. You definitely have to get them before you can drive the car.

Yea that sounds right, It is about the thickness of a regular pvc pipe, What are the rings made of.. I could possibly improvise something... Or do they also space the rotor off the hub a bit...

Sucks man i wanted to do Stoppies this weekend....

 

[VTEC_THIS]

It's a thin metal. I don't know if I'd make something...what if it broke while driving. The rotor would be chattering around and can possibly chip or crack, plus you said it was making a really nasty grinding noise just while in the driveway - imagine that while on the highway. You might be better off just calling Baer and having some rotor rings or centering rings overnighted to you.

 

[4Motion4g63]

Yea thats what I will halfto do....

So does it also space the rotor off the hub too? Seems REAL close to the lower control arm...and it scared it where it was rubbing a goood 1/8 inch into the rotor brake surface, but only slightly rubbed it...

If you are looking at the back of the rotor from the inside edge, it scared 1/8 From the Inside into the braking surface area from the inner edge...

It doesnt space the rotor, just centers it up on the hub. You need to do some grinding on the lip of the control arm.

 

[4Motion4g63]

I guess the brakes already shaved some metal for me....
So you do need to grind a little, There were a DOZEN washers/spacers in the box of bolts that came with them i Imagine they were behind the rotor on the studs to clearance them slilghtly

FYI there the 13' Slotted Rotors, With Twin Piston Calipers, I picked them up for $200...

The rings are (red) aluminum and do not space the rotor out at all just center it. I had to take a wire wheel to the hub to clean all the rust and grime off. The rings fit on real tight so the surface needs to be clean. I did not have to do any grinding at all, my kit bolted on right out of the box with no problems.

Yea I will see about the spacing and clearance after I install the rings, they were cheap about $2.50 and i got them comming...

Rings came in and were a PITA to put on, Dont fit inside the rotor but do fit the hub...
I still have grinding in the lower control arm after a ton of clearance and metal removed...
I Will put some washers behind the rotors and space them off the hub now..

My rings were not Red but A dark bluish purple...

 

[need2boostpsi]

got any install pics? sure would be helpful, plus you don't see many 1g's with 13" rotors.

I think you might have a 2g brake kit. A while ago I ordered a set of AEM big rotors and relocating brackets for the stock calipers. I also had a huge problem with the rotors rubbing against the control arm. I did grind the control arm a bit but it still touched. Turned out it was a brake kit for a 2g and not a 1g/gvr4. I sold the setup and got a 1g BAER Track setup.
Setup doesn't even come close to control arm.

You need to get the centering rings for the rotors from Baer. That way you know you'll get the right ones.

Don't put washers behind the rotor just to make it further away from the control arm. That will put more stress on the wheel studs and push the wheel further out also..

that sounds right for the problems ive had....BUT they came off a 91 and were working fine...
I am trying to contact the guy that had them...

I have seen 1g kits with 12's rotors but NEVER 13's rotors

I did get the Spacer rings from Baer, Fits the hub with some light coaxing, but I am forcing the fit around the rotor...

Ask the previous installer what all he had to do to get them to fit. I have the PDF instructions for both the 1g and 2g setups. I'll email you a copy that way you can have the reassurance that you are doing things right.

You are right, I have only seen 12" rotors on 1gs, not 13". Either way, you should have double checked the intventory, or did some research online about the kit before you got yourself into this mess.

I have the 13" 2 Piece rotors for my front kit, and Evo 9 for the rears... I had gotten the install done in a flash. I bought everything brand new of course.

Of course its going to be tough around the hub, but make sure you are evenly applying pressure, not just in one spot. And as far as the rotor fitting, its a floating rotor, so you are going to need to set it on the ring, and when you bolt the calipers and brackets on, be careful as to watch the rotor, it may have shifted from its original point. Just keep the rotor positioned correctly til you bolt everything back up. Then, once you give it the final torquing of the lug nuts, it should be fully flushed and centered. If not, you have more problems, (like your control arm interference.)

Double check your steps.

So in theory, I need the different bracket and rotors and should be able to use the same calipers, I am stuck with the kit... or else...

I will try to space it with some washers, the box with the brakes that they were packed with were full of them... and there were 2 marks on the back of the rotor where it had rubbed the lower control arm... maybe it will be ok with my clearance and some washers...
I wont be driving it much or hard on it till i get the right brackets...

what is the part number for the rotors?

Here are the 13" rotors on my car. It's a gvr4 but same as a 1g.

To me, it sounds like the guy before you rigged them to work for a 1g, in spite of all those washers and marks on the rotors. If you use those washers (just like a spacer plate) you will need to adjust your camber and toe (caster will not be offset). Meaning you will need a wheel alignment thereafter. It will also cause undue stresses on your ball joints and hub. Due to the offset being different, and your turning angles being slightly different, it will need to be adjusted.

BUT, if you had the right kit, with all the inventory (like I stated above) you will have not a problem installing this kit. It should be a remove and replace job, not customized and hacked at.

Double check with the guy to make sure they are from a 1g.

Very nice and clean. I powdercoated mine, black for the caliper, and red for the bracket. I am going to get my Brembos black as well, right now they are red... But oh well. Its about show and go.

And regardless of your driving habits, your brake system is the only thing to stop your car. If that fails, you can attempt to use the trans as an engine brake, or even the parking brake, but that won't do you any good. I wouldn't drive it until its fixed properly. Then I'd season them in...

 

[4Motion4g63]

I figured out my issues.....

I have a 2g kit...



It will cost $525 for the right parts to make this one work...It may or may not be for sale soon Anyone know anyone with a 94-04 Cobra Mustang with some spare brake rotors?

 

[VTEC_THIS]

That sucks man. Sounds like some negative feedback is in order. The seller sold it as a 1g kit and it's really a 2g kit, that's definitely not cool.

If I were you I'd sell the kit and buy the 1g kit. In the mean time, put your stock brakes on so you can drive the car.

I kinda guessed it, but I didn't want to say anything yet. Now its confirmed. Sell the kit, use the money to buy the right one. You can't complain though for the deal.

Haha Well I would Give Negitive if it was'nt My Homie, He bought 1g with them already on the car.. So he did not know
Himself....

I Did find a Cheap work around on this setup....
The brake setup is stock for 94-04 Mustang Cobra Cars, So I went to autozone and order the 13' stock replacement rotor for $48 Ea. And Since the Rotor is CLOSER to the rim I just need to remove the Lower Spacer/Washer on the adapter mount and add washers if needed.... I can also find cheap ebay slotted drilled rotors for the mustangs for about $180 a pair...

Should end up at $300 for a nice brake setup when all said and done...PROPER
I will update with Finished pictures as soon as the rotors are in and on the car...

New Rotors Are IN and cost me $98 total, I Will put them on later in the week I will take some pictures...

BIG Difference in offset, almost worries me that it wont clear my 3g Eclipse stock wheels....

Told you !!

 

[4Motion4g63]

Well I made the 2g kit work on the 1g.....

The rotors AND calipers must have been different from what i had..

I bought wheel spacers and put some behind the rotor and that has worked out great.

They fit and center up still using the centric ring it was only a few millimeters of clearance needed....

Are you saying the baer calipers are for a 1g, and you had 2g rotors, or vice versa?

Could you please explain in much greater detail exactly what you did to make this work. Step by step, would be nice.

This would be much appreciated.

Later Dr Turbo

From what I understand, The brakes were originally came from a 2g that a friend had...

He sold them to a guy with a 1g, Somehow the were installed on it...
My buddie bought that 1g with them already installed, removed them parting the car out and sold me the brakes....

I had lots of problems getting them to fit, mostly from the lower control arm hitting the rotor.

I had to grind some of the lower control arm down to clear and then added a washer under the caliper bolt/adapter, and put a equal size wheel spacer under the rotor, the centric ring was incorrect but after some sanding fit fine.... I think with the proper 2g centric ring the fit would be no issue...

I thought buying the 1g rotors for the bear kit ( witch are stock mustang Cobra Rotors) would work to fix my rotor clearance issue.. Yea the 2g kit was a 12' rotor and the cobra 1g rotor is 13' rotors would not work, so washers and wheel spacer will make it fit for 1g using a 2g bear brake kit...

Thank you for your response, but you did not tell me what rotors you actually ended up using, my guess are the ones that came with the kit you bought from your friend (which are??? and please don't guess if you don't know just say that). Second the Baer kit offers 12" and 13" kits which have different adapters where you trying to use the 13" rotor with a 12" adapter? Also, there is no proof out there that backs up the 1g Baer kit uses Cobra rotors, could you please verify your source proving that true. There was a alot of discussion of guys trying to use them as replacements but they did not fit. This may seem as though you already answered the question, please be patient, I want to understand you very cleary, that is all.

Thanks Dr Turbo
