NWZ Posted March 14, 2009 Share Posted March 14, 2009 Garage advised discs have a lip formed (which I knew about), it's only very slight and the garage said they should see the pads out. Trouble is the discs (DBA's) have been on the car for 38k so far, I replaced the pads 9k ago with Ferodo's from ESR. My question therefore is, how do you know when the discs need replacing - is it a case of measuring how thick the lip is? I cannot imagine these discs seeing out the pads as I reckon there's a good 21k on the pads left. As always any advice appreciated. Quote Link to comment Share on other sites More sharing options...
Beavis Posted March 14, 2009 Share Posted March 14, 2009 Its normally when the disc gets worn down to a certain thickness iirc Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted March 15, 2009 Share Posted March 15, 2009 For reference, the new thickness and minimum thickness for the discs are: Brembo equipped cars: Front new thickness: 30mm Front minimum thickness: 28mm Rear new thickness: 22mm Rear minimum thickness: 20mm Quote Link to comment Share on other sites More sharing options...
Chris`I Posted March 15, 2009 Share Posted March 15, 2009 Basically when you get a 2mm lip on them, its time for a change. Pretty much as CS said Garage or Quick Fit can measure them with their callipers if you think they are worn How many sets of pads have you used on the discs so far?

NWZ Posted March 15, 2009 Author Share Posted March 15, 2009 Thanks for the advice guys! Don't get me started on brake pads !!! I've had 3 lots of pads on these discs:- 1) Endless sss pads for 28k - they caused stripes on a couple of the grooved discs and caused rusting - looked terrible. 2) Endless CCX pads for 2k - terrible pads imo, terrible brake pedal vibration when braking hard from 70 mph (being modest ) - tried bedding them in but wouldn't have it - Spoke to Phil ESR who sent me a set of oem's FOC God bless him. 3) Now running OEM's for 9k so far without any problems. I wont be using Endless pads ever again- just a bad expensive experience if you ask me. The discs have been pretty good though - especially to see over 40k !
