I pulled down the front right corner for replacing the ball joints and during the process I noticed that the ventilated disc was barely worn, yet the outer surface had one 2" surface crack. The casting doesn't seem to have cracked through to the ventilated space and is not cracked on the inner. I'll have to check the other 3 corners later as the car is sitting on 3 tyres with 3 more stands but all new discs were the Brembo brand. Has anyone had similar problems with surface cracks of any brands, and why do they surface crack? I haven't towed at all since I installed these brakes, and they brakes haven't got even warm since then, so .... I went to the local brake supplier in Woden and found they could order discs for the P38, RDA for $100 for one front single disc, but I thought that none were cast, heat treated or machined in Australia any more. So all are manufactured and imported, mostly from China, including DBA or any other no-name ones, or aren't they?
I fitted DBA Slotted discs front & rear with std pads also stripped down all 4 calipers & re kitted them as I found they were almost seized giving a hard pedal but little pressure obviously. I also fitted braided hoses all round. The change is remarkable much better feel & response!
p.s I also re-kitted master cylinder with S/steel discs replacing the fragile oem plastic units.
Dont take chances with brakes!
on my VW transporter I recently had a disc disintegrate (one side only)https://uploads.tapatalk-cdn.com/202...97bf2dd4d4.jpgQuote:

When I pulled over and had a look I could not see a problem as it was the inner side of the disc and the van is so low I couldn’t get my head around to look from the inner of the car
I drove home only using the handbrake and gears to find the problem when the van was jacked up
We now realise the shudder must have been a cracked disc☹️
If I was very clever, which I'm usually not, I would carefully clamp a ventilated disc, vertrically and parallel to the blade on a bandsaw, and slowly cut through the vented 'middle' pattern, this would look this picture. But how could this disc fracture evenly, yet it seems to not spin or rotated without chipping or locking the casting bits? I have, though, seen this machining process of DBA advertising of their new pattern disc castings, so it is do-able. Ummm.....
