Does anyone know what a 2945 booster was used on? What number booster should a 67 Camaro with drum brakes should have? Thanks sincerely Brian

According to the Delco Moraine Service Manual dtd 1-70 '2945' is for a 1967 Pontiac Tempest with drum brakes. It has much higher output PSI than the Camaro unit.

A 1967 Camaro would use '0749' or '1109' with metallic brakes.

BTW these are the numbers on the tab, unrelated to the part number.

Wasn't there also a difference between boosters for drum vs disc brakes with the booster for drums having more capacity?

I don't have the detail booster part numbers - maybe William or Ed have them. They're shown as different numbers in the A.I.M. between J50 (power drum) and J52 (power disc/drum), but that's because those numbers are for the complete assembly (booster and master cylinder), probably as a result of the drum master cylinder and the disc/drum master cylinder being different.

The A.I.M. also doesn't show the correct releasing of the parts - the booster and master cylinder were received separately at the plant (not as an assembly as shown in the A.I.M.); the booster was installed on the body on the Trim Line, and the master cylinder was installed on the Chassis Line where the brakes were bled. The master cylinder was pushed forward out of the way, and was attached to the front of the booster (or to the pedal support studs with manual brakes) with two nuts after Body Drop.

Boosters are rated by output PSI at 20 and 100 lbs pedal pressure. In general disc boosters [so identified by "1-1/8 piston dia"] have higher PSI than drum.
