I have a friend who has recently bought a Mini Cooper.

Basically the car is an 02 plate, and the only non factory mods it has are a lightened flywheel and K&N panel filter with plugs.

However, when we collected the car the bloke was saying how he had the brakes cleared and the pads were replaced with mintex ones. On the way home we stopped off for a break and he was telling me how the brakes did not feel as responsive as they should.

I then drove it and the brakes seemed ok, a bit on the spongey side though, however once the ABS kicked in, the pedal travelled straight to the floor and the vibration through the pedal nearly took my leg off. They were not like mini brakes whatsoever.

So when we got the car home, we purchased some standard pads, and bled out the whole system to get all the air out. But even though the old fluid looked nackered and as if it had been boiled, the brakes were not much better after. The pads have been fully bedded in, and i can 100% guarantee there is no air left in the system. We also cleaned the ABS sensors but this didn't do much.

We are all out of ideas and were wondering if anyone else had any similar troubles, or suggestions.

Thanks

To quote from the Bentley manual "Once air enters the hydraulic unit, it is very difficult to remove using traditional methods. For this reason bleed brakes using a pressure bleeder and a large supply of fluid" The hydraulic unit is part of the ABS. The Haynes manual goes further and says once air is trapped in the ABS regulator unit you need to take it to a MINI dealer or a specialist. It needs special electronic equipment so will probably be very expensive. Hope this hasn't scared you as I haven't ever heard of this actually happening. Definitely only think about this once you have exhausted all other possibilities.
