Les Richmond Automotive has had a troublesome master cylinder seal custom made. This seal is available through Land Rover but only in a full kit at a couple of hundred dollars. We now have it separate at a fraction of the cost. The seal we are referring to is the master cylinder reservoir seal found on the small black master cylinder. Range Rovers from 1997 and Discovery’s. This seal causes an external brake fluid leak but be assured it is cheap and easy to repair.
