Older cars that have been used regularly have a lot of corrosion, the brake petcocks are probably rusted. Although there is a considerable amount of aluminum in the RR, the petcocks are not, be careful and have some replacement petcocks or you may find yourself draining the entire brake fluid. Apply a penetrating oil product the day before you start the project. Additionally, have an ample supply of new, sealed bottle of brake fluid available for the job. Note: Brake fluid reacts with the moisture in the air, so use a fresh supply.
