Moraine boosters are anodized and held together with locking tabs, while Bendix are painted & assembled with screws. Note that the Moraine booster has only two studs for the master cylinder, while the Bendix has four.
#1962 THUNDERBIRD BRAKE BOOSTER REBUILD KIT INSTALL#
The left hood hinge might need to come off in order to remove or install the tank. The tank itself attaches to the inner fender with three bolts accessed by removing the left front wheel. It's not much fun having your car laid-up unexpectedly while waiting for parts, but ensuring that it has reliable brakes is one of the most essential things you can do for your own safety and that of those around you.Īll '61-2 full sized Olds with power brakes used the vacuum tank.īoth the Bendix & Moraine boosters came with an integral T-shaped connection, one side of which went to the engine, and the other to the tank. By the time I was done, the whole brake system was new. That scared me enough to go around the car and check the wheel cylinders, which weren't much better. I wound up with both a rebuilt booster and a sleeved master cylinder, which took care of the problem. The bore in the master was very badly pitted, which tore up the seals on the piston. Then I removed the master & booster, and discovered that the booster was half-full of brake fluid that had leaked past the piston in the master cylinder. I would take a good look at your master cylinder, particularly if you've never had it apart.Ī similar situation occurred to me years ago on a '61 Olds with a soft, sinking pedal. If anything, it would be more difficult to depress the pedal with the loss of the vacuum assist from your booster.Īre the master and booster still on the car? While the hissing certainly indicates a vacuum leak in your booster, a bad booster alone shouldn't cause your pedal to sink to the floor.
