Drum brake Booster

I bought a brake booster for my manual drum brake '70. Can I add this in and use the stock master cylinder without modifications ?

Re: Drum brake Booster

Yes, but you will need the correct pushrod, it is not the same as the manual brake pushrod.

The booster I bought came with a short and a long pushrod. Is there a different one from those ?

Re: Drum brake Booster

I am referring to the pushrod that connects to the brake pedal. There is also a short pushrod that sticks out of the front of the booster.
