Anyone had problems with dba disks? Got new disks fitted a while back and within weeks a was getting judder under breaking so I had them skimmed! Then few weeks after I'm getting brake juder again!! They haven't had any sudden change in temperature to cause then to warp and the car gets used everyday so it's not build up of rust either... saved for ages to be able to afford new brakes coz the old ones were warped like hell and I'm having the same problem!! Bit pissed off really!

That's your problem then the Ferodo compound suffers from transfer onto the discs & its this that causes the judder not the disc swap out to an alternative pad like performance friction & it will cure the judder.

Thanks, where can I get different pads from? When I had then skimmed few months ago the place that did it confirm that they were warped! If they are this time again can i request that whoever sold me the disks send me replacement disks? Just pissed off Coz a have a sty paid job at the moment and can't afford much

I'm not crazy about my DBA discs either. They work just fine but the disc / pad combo I've currently got produces a crazy amount of squeal under low pedal effort frown

They might be cheaper and better quality over AP's but at least with AP discs and RS29 pads they didn't squeal unlike the current setup. Can't wait till I've chewed through them to be honest so I can swap to something else...

I've had DBA grooved discs (42020 I think) and Performance Friction pads on my VZ for two years with no problems at all. Good quality and easy to fit. At less than £400 for the discs and pads, they were cost effective for me.

The pads take a few hard stops to get fully up to temperature though, apart from that, they're excellent and the discs still look like new smile

I too constantly have this problem my rear discs have been skimmed 3 times now and problem has reoccurred again
I've just accepted this as normal now as it cannot seem to be rectified for long

I've got squeal on the rear Wortecs at low speed. It could be as the pads are too hard for the application. Are you using the pagids on them?

Pagid RS29 all round. Get squeal from the front too whereas I didn't with AP discs.

I'm due a rear caliper rebuild so hopefully that might help. We'll see.....

I have DBA discs with yellow stuff pads. No squeal, no material transfer but good for use on track. The only downside is the amount of brake dust on the wheels.

I had issues with material transfer on my old VXR discs but this only happened on track.

Lots of work to do on the Firebird...and then some!

No jobs on mine this time, as I had a 3.90 diff and True Trac fitted last month.

Very nice. Notice the difference in acceleration I bet!

Yes,the 3.90 really wakes the car up, a worth while mod.You are welcome to try it if you want.
I still have an awful clunk though. I was underneath the car today and I managed to turn the prop by hand a full 13mm before it stopped. That seems a lot of rotation to me!

Next year its brake disc's and shocks all round.Then put some miles on it!

I have also had an issue with the DBA discs. Fitted new discs and pads all round about 7 or 8 weeks ago, I won't talk about the amount of trouble I had getting one of the rear pad pins out!!

All seemed to be fine, but after two weeks had massive judder from the fronts under any type of braking, it was awful. Didn't have chance to do anything about it before driving to Le Mans for the Classic 24 hr last weekend. But I can say that since the trip they seem to have sorted themselves out and the judder has pretty much gone. I'm running APF 404 pads which are similar to Ferodo DS2500's.

I am in the process of having some larger front discs and calipers designed and made, using AP CP8317's and matched AP rotors with custom bells and brackets. So hopefully this will fix the issue.

The DBA discs were certainly well within tolerance when new as they were measured for trueness on the bench.

Sounds like you had pad transfer then but they cleaned up?

There is a good chance that was the case.
