Customer Question

A petrol rover 25 with abs and 4 caliper brakes. When driving and attempting to brake the brakes slow the car slightly and the pedal goes goes down to the floor generally leaving the car still rolling forward making it feel like air in system. Master cylinder
& brake servo ok and system bled numerous times. No apparent loss of fluid and no evidence of such anywhere. Problem started when an MOT garage changed rear near side brake assembly due to corrosion and not functioning properly. Lastly no abs light on dash.

Hello its possible that you need to run the ABS pump to move any trapped air inside the pumpthe dealer method is to use the diagnostic tool to cycle the ABS during bleeding however I've had good results buy just taking the car for short drive and stamping on the pedal at low speed to lock the brakes and trigger the ABSand then re-bleed
