I've recently upgraded my R34 brakes to 6-pot 343mm APs with DS3000s.
Now they stop very smart from cold, almost too sharp, squirming under heavy braking.. but that's OK.
The thing is, after 1-2 laps of Elvington airfield, they're knackered, with the pedal going very spongey, and needing pumping to get them to work. The old brakes lasted longer than that !!!
I've had them bled since, just to check there's no trapped air, but it still happens.
Any ideas ?
