Hi. This van had brake pads fitted somewhere else but came to us with front brakes binding. Noticed it also had a new master cyl. Customer said the brakes were fine until brake pads fitted. 10 miles down the road the brakes stuck on. The garage fitted a new master cyl. Did all the usual checks. Brakes ok unless they are used a lot and get hot. Slacken master cyl bolts at servo the front brakes free. Remove vac pipe at servo, brakes still bind. Going towards servo but have you any ideas why this could happen.
Regards
Les
