Yep.

The boost type does not affect fluid flow through the base brake system.

Re: Hydro - boost brakes

That's funny. On vacuum boosters, the pedal gets hard and very hard to stop. This pedal is not hard, in fact goes to the floor only like there is no PRESSURE. does stop but scared when it goes to the floor.

Re: Hydro - boost brakes

Does the pedal get higher when repeatedly pumped? If so then air in the system.

if not then

sounds like master cylinder is leaking internally

Re: Hydro - boost brakes

No it doesn't pump up, I just didn't know if these brakes were the same as the vacuum booster brakes

Re: Hydro - boost brakes

As far as I know the brake hardware in the wheels is the same,maybe differences in wheel cylinder diameter, but I don't know about the master cylinder of the hydro boost being the same as the master cylinder of the vacuum booster .

might surf to auto parts place website and get part number of each and see if they are the same. They might also may have picx

Re: Hydro - boost brakes

my suburban has hydroboost and you bleed them just like vacuum brakes. I lost my brakes and found the master was leaking out the back.
