bedding in brakes question?

Postby lil » Thu Feb 17, 2005 5:03 pm

I am installing new pads and rotors on my aw11. The questsion is should I bed the new pads in on the old rotors or not?

I have the pads but wont have the rotors till next week so I figured I may aswell put the new pads in and use them a bit before putting the new rotors in. Will doing this create any problems?

The pads are green stuff, if that make any difference?

It always to pays to bed new pads on older rotors & new rotors on older pads this is just to minimise any chance of glazing. We've done race applications when we've had no choice but new pads & rotors & the only bedding in was the warmup & pace lap at the start of the race. Doesn't matter if you bed your new pads first or the new rotors. Not 100% on the bedding procedure from EBC greenstuff, the supplier should be able to supply you EBC's recommended bedin procedure.

Really?? 500 km for racing pads, thats alot of kms. Not saying you or the box is wrong but thats a long distance for a race car.

The pads I use in my road car which are basically race pads, get about 10-20 light stops to knock the high spots off them, then they get death for 4-5 hard stops until I can just feel the pads loose there edge, then they are allowed to cool fully with minimal brake application. They have never glazed up & seem to last alright & the way above is the way the manufacturer recommends to bed htem. We get some mintexs which you pre-bed before install with a gas torch, cook them up, install them & go race on them no probs.

I have put the new pads in with the old rotors and been for a drive round the block. The pads dont seem to require any warming at all before working, they seem fine first pop. :)

I will give it 100kms or so and then they can have some punishment.

Box says "avoid emergency braking for the first 320km", I dont think I have the self control to wait that long!

Super cheap auto's had DBA standard rotors for $123inc ea. But my local brake guy is getting me some other brand (Australian I think) for $112inc ea. I will put them in next week.

The guys I buy brake stuff off said that they prefer to bed new rotors with old pads, then put in the new pads. But you can do both at once, but you have to be kind to the rotors at first by driving a few hundred kays in normal road use. Something to do with letting them heat cycle and settle.

He didn't recommend bedding pads in with old rotors, then slapping on new rotors because some pads don't bed well to the new rotors and will not perform at 100% for some time, or may wear the rotor a little unevenly at first...
