SOURCE: Brake goes to floor with new mater cylinder question about power booster

If your pressure is good in till you start your truck it is the power booster. i just fixed this problem. If it is not your master then that is the problem. I had to replace the whole brake system to find this out.

SOURCE: hard clutch pedal

You cannot bleed a servo. it runs using the vacuum from either inlet manifold, or a seperate vac pump.Ensure pump is working if fitted (end of camshaft) the pipes to the servo are not leaking by removing the pipe from servo and start veh. If there is good suction then its servo failure. hard pedals can also be caused by pressure plate fatigue in the clutch itself.

SOURCE: replacing power brake booster

You don't need to remove the pedal to get the booster off,it just slides inside,so when the booster is unhooked it will just pull out.

Why is it so hard to apply brake pedal?
_______power brake booster, check vacuum to booster and the check valve for brake booster. primary symtom is high hard pedal that requires greater then normal pedal pressure to stop car. testing booster= pump brakes several times with engine off to deplete stored vacuum. turn on engine with pushing slightly on brake pedal. you should be able to feel the pedal fade away a bit, and then become firm. But not hard. if you feel nothing at the pedal when engine starts. Brake booster is not working. Good-day! make sure vacuum is going to booster with engine running. it may just be a bad vacuum line or check valve.

2002 Montero has high pitch sound from dash and brakes are hard
it sounds like you have a problem with the brake booster it may be a leaking seal that is causing the high pitch sound if you are losing vacuum you don't have any assistance from the brake booster hence the hard brake pedal....cheers

Brake booster appears not to be working properly. brakes work ok for 1 or 2 apps then pedal gets hard. cannot hear any vacume leaks. the car does have a vacume switch in the booster
the booster is the problem, or a hole or leak in vacuum line to booster check the check valve also ! from manifold. heres the symtoms of a bad brake booster. primary symtom is a hard pedal on application, to test booster. pump brakes several times with engine off. to deplete stored vacuum. turn on engine with pushing slightly on brake pedal. you should feel the pedal fade away abit and then become firm. but not hard. if you feel nothing at pedal when engine starts, brake booster is not working! check the vacuum lines first!!

Brake pedal is hard and vehicle is hard to stop, what could be the problem?
servo assist could be faulty
best way to check is
push pedal a few times with engine stopped
press down on brake pedal ,and at the same time start engine
the pedal should travel down more if your servo is working properly

I can hear a hissing noise coming from the brake pedal on my 2002 Ford Escape. Its been there for a little while. Sometimes the brakes doesn't work properly, it feels a little spongy sometimes. But usually...
It sounds like the rubber diaphragm in the brake booster has developed a leak producing the hissing / sucking noise. The only option is to replace the booster as a complete assembly as they need specialist tools to repair. If the booster fails completely you will still have brakes but the pedal will be very hard and it will take a lot of muscle power to stop vehicle. Best to have booster replced soon before you experience situation described above.

My brakes are hard to push down and it sounds like air is coming out of the brake pedal
This one I can be fairly certain of. It sounds like a rip in the vacuum power brake booster diaphram. Usually you just replace the whole power brake chamber, which includes the diaphram. You have to first remove the 2 bolts holding the master cylinder to the larger booster chamber, but you don't normally have to open any brake lines.
When replacing, make sure the brake pedal rod goes down the center of the new booster, and that there is sufficient clearance or freeplay in the pedal rod when done. (like .1" is all you need)
Should not have to bleed after done.

2002 volkswagen passat turb 1.8 brake fault code after installing a brake booster now I have a hard pedal
Hi if you have a hard pedal, i would suspect you have an air leak on the servo pipe which goes to the brake servo, this is the same pipe that the brake booster is attached to, if you run the car and listen you should be able to hear the air hissing out from somewhere, hope this helps Chris
