My 90 mustang Gt stock booster doesnt get enough vaccum after i swapped h/c/i. its hard to push the brake pedal down. Will one of these boosters fix this problem and what part do I need for it?Also I try a vacuum Reservoir it didnt help at all.
Changing the booster wont help.Its the camshaft that produces vacum for your brakes,either you have a crazy ass cam in it or you have a very large vacume leak somewhere on the engine itself.
I just went out and started the car and rev it up and mash the brake I can hear air from the booster.I thought all car make that kind of noise when you push on the brake.
