Are you getting loads of vibration coming through the pedal when braking at low speeds coming to a stop, it feels like the abs is kicking in, if so ive had the same problem for months ever since a local garage adjusted the handbrake, the only problem is that it dont happen all the time just every now and then, its been driving me mad ive had brakes,disks and calipers changed. going to try changing the fluid next week,
