:eek:oohhh:my brake pedal, this is. I swapped out my front calipers and discs for the brembo 4 pots with 324x30 discs from an 840ci. I have bled the brakes twice. The pedal has far too much travel for me. Do I need a larger brake master cylinder? I wouldn't think so because the ATE four pots with bigger discs from the 94-95 M5 models still use the basic cylinder. Or am I wrong about that? Any suggestions would be greatly appreciated! Thanks

Well, any new brake combo will need time & miles to bed in properly...

I'm assuming you've put new pads in as well ?
These will take probably 250 miles of moderate use to function properly.
Initially the pedal will feel quite spongey with new pads on board.

Did you bleed all four calipers ?
You'll need to do all four as air will have found its way throughout the system.


Regards,

Alan.

I did bleed all four calipers starting from the passenger rear, in order of proximity to the Master cylinder. Thanks for the assurance. Its funny though, I haved changed the pads on my Disco, my iX and the M5 many times without the sponginess. I hope I don't have a leak somewhere. The car is not spotting brake fluid.:confused:
