I'm researching whether the 4-pots I have just fitted have the preferred piston size for the brake bias/master cylinder matching.

If anyone could let me know the piston size for the Prodrive 330mm upgrade, it would be appreciated.

 

41/34mm to keep the balance right. Most other kits have 41/38 which sometimes gives a feeling of more bite but that's because they are doing too much work.

Cheers Mike,

I was going to PM you but didn't like to bother. Thanks for replying.

Mine are 41/38 so pretty much along the same lines as you have stated.

I think my problem lies with poor cold perfromance from the HAwk HPS pads.
Once they are hot, boy do they work .
Although I'm never going to get them that hot with the wife and kids in the car

Any recommendations (FRP501 Pad style)
