Or should I not waste my time and get new rotors? I'm happy with the bendix pads but are there anything else I should try? Cheers Mike.. Link to comment Share on other sites More sharing options...

Who put your rotors on? shop/friend? was the runout checked after installation? cheap pads will wither wear out quicker or not stop you but shouldn't cause shudder. If you however have warped the rotors or created hot spots from braking a lot then throw the rotors out. Link to comment Share on other sites More sharing options...

Cheers Mike..Machine slotted rotors is time consuming and will cost more than standard as they can only be done 1mm at a time without causing damage to the tool...

So if I get them machined and better pads it should be ok? I just dont wann go to the hassle of gettin them machined, get the new pads on and end up with the same problem 2 months down the track.. I'd rather do it right the first time..The rotors were put on by Pit Lane and were fine for ages, but I guess they have gotten crap over time and the shudder is really annoying now.. It happens at higher speed say 80-100kms/h when I brake lightly, if I stomp on it it doesnt shudder it brakes normally.. At lower speend 50-70kms/h they are fine..

DBA's and Bendix pads are know to not get along. I'd suggest different pads and possible front control arm bushes judging by the symptons you describeOH and I had my 4000 series rotors machined and it was no problem. Its pretty rare that you would need too remove more than 1mm when machining as the difference between new and worn out is only 3 or 4 mm Link to comment Share on other sites More sharing options...

U think the front control arm bushes could be responsible? are they something I can change myself?I've used the DBA and bendix combo for ages with no problem..

A BA @ 150k Kms I'd be looking at front suspension bushes. Unless you have a workshop with a press, you wont be able too change them yourself.You could remove the parts and get the old ones removed and new ones fitted, or Get in touch with Pat (Senna_T) as I'm pretty sure Wholesale Suspension Products have exchange arms.I'd got superpro bushes while your at it Link to comment Share on other sites More sharing options...

If you are lucky you will get away with it. If you have access to a dial gauge you can check if the problem is with the hub or the rotor.

Yeah Super pro for sure, ideally I want to Super pro the whole car but my wallet doesnt agree with me..Paulie, that's exactly what I dont want..

Both the front upper and lower control arm bushes and struts are worn.. Could this be the cause of the shudder I'm getting at all? Could it be making a small shudder worse, to what I'm experiencing?
