Need some help with Brake issues

I'm jealous over your garage floor!

it is a disc / drum from the looks of it, that's all we can say from the photos.

The master cylinder that I received is a little bit bigger but it is for a power brake front disc rear drum car.

when you say a little bigger do you mean physically bigger than the old one or the piston diameter is bigger?


and can someone answer the question for me about the pushrod keeper in the cylinder manual vs power?
