<< I have two questions that have always puzzled me 1) Why are brake boosters (and therefore master cylinders) sometimes mounted at an angle? Why are the brackets not such that they are essentially level? 2) Why do they tell you to bench bleed a master cylinder on a bench vise and not with it attached to the brake booster so you can use the brake pedal to activate the plunger? Doing it on a bench vise is a real pain in terms of activating the plunger. Thanks. john >> The brake booster needs to be on an angle to clear the valve covers. You need to bench bleed it in the vise so that the master cylinder is level, If you do it while in the car attached to the booster, you will have air bubbles in the master cylinder and the brakes will not function properly. I bench bleed master cylinders all the time in a vice and it's not that hard, just use a blunt end screwdriver. Tom
