Hi,
The brakes on my Astra have become very spongey. Even with the pedal right down it still doesn't stop the car if going fast enough. I bled and rebeld the brakes five times but it still not sloved. I'm not losing any brake fluid but there's air getting into the system. I've been told it 's the master cylinder.
Is it a straight forward task to change the master cylinder. Is there any speacial tools needed. Can i get a second hand master cylinder or is it better getting new.
Cheers,
Doug.
