Changed brakes and rotors on 2005GMC Envoy,now brake pedal is hard when not running and soft when running?


This is the usual behavior. When the engine is running, it is generating a vacuum, which pulls on a diaphragm in the brake booster. This is what is called "power brakes". It uses engine vacuum to help push hydraulic fluid thus reducing the amount of pressure you must apply to the brake pedal. When the engine is off your foot has to make up for the force that engine vacuum usually applies, which makes the pedal feel much more firm.

I have a 2008 equinox. after driving 20 mins in stop and go traffic, brake pedal becomes hard and can't move the car. Replaced master cyclinder, brake booster and brake pedal sensor. Help


Check the flexible brake lines on the front two wheels. The rubber inside can become swollen which will restrict the release of pressure when you let off the brakes. After a few brake applications, enough pressure will build up to keep the brakes applies to the front two wheels. It will also severely wear the front pads .

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.

2009 Dodge Caliber - The ABS & Brake Light came on as well as the feeling/sensation of the brake being applied very hard for a split second.


take it to an accredited brake specialist shop
I suspect that the brake booster is becoming defective and the small application to the pedal causes excessive booster reaction
the abs section only maintains applied brake fluid pressure as set by the position of the pedal
that is to maintain the pressure as the stopping and start movement of a skidding wheel opens and closes a valve to that wheel /s
if you are on ice that sudden hard braking will cause the wheels to lock and immediately the abs cuts in to allow the wheels to turn and then to allow brake action to be reapplied
if the abs is working under brakes you will get a pulsating feeling under your foot as the fluid pressure is alternation between full on and released by the abs valves

Metal on metal noise when driving. Sounds like brake noise when brake pads are in need of replacement. Sound goes away when the brake is applied. Car only has 20,000 miles on it (2006).


Hello tgiro7: My name is Roger and I will help with your question. The fact the noise goes away when stepping on the brake pedal says the problem most likely is in the brake area. The pads could be worn out even at 20,000 miles.If the noise sounds like it comes from the front remove the wheels and check the front pads. If the pads are bad most likely the rotors are also bad.Same would apply if the noise emits from the rear. When you have the wheels off check to make sure the calipers will slide in and out on the mount pins. Should they be stuck on binding the pads will wear excessively and prematurely fail. The calipers must move freely on the pins. If you drive with your left foot on the brake pedal? The amount of pressure required to apply the brakes and not stop the vehicle is 1 to 2 pounds of pressure. Wont turn on the brake lights but will put pressure on the calipers. This in turn will wear out the brake pads. Another thing to look at would be an out of adjustment brake switch. Reach down and grab hold of the brake pedal. Give a firm tug on the pedal. Should you feel the pedal give and hear a click or two the switch was set to deep and holding the brakes on.
Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

1992 F250 460 cid automatic 2w drive 85000 mi. Just replaced my master cylinder, all 4 brakes, and both front rotors. Afterward I blead the brakes and got bubbles out of fluid. Problem is : when not...


There is never a test or reason to pump your brakes

Accomplishes absolutely nothing.

There is no pressure in a braking system at all,
until you SLOWLY apply the brake pedal.

Then less than 1" off movement in the master cyl,
will develop 600 to 1800 lbs at the wheels

Release the brake pedal, the system goes to zero,
IT DOES NOT HOLD ANY PRESSURE

To answer your question

You not suppost to press the pedal hard
The saying goes--you apply the brakes,
not force the pedal arm and pin into the
vacuum booster, as though you want to damage it

When your driving what happens ?
You have higher manifold vacuum and
thus your pedal is normal,why the VACUUM

On my 2004 Jetta 1,8T the brakes are starting to get hard. Taking s little more pressure on the brake pedal to stop the car. What could be causing this??? Thanks


The most likely cause is loss of power assistance to the braking system which means you will need to apply increased brake pressure to compensate for the loss of assistance.

The problem will be with the brake servo assist. It is possible there is a leak in the brake servo assist system, which reduces the vacuum, so you are not getting sufficient mechanical assistance when applying the brakes.

It is unwise to be driving the car with this condition. If you lose all power assistance to the brakes, which could easily occur with this fault, the pedal will become very hard, you will need to apply very high pedal pressure and the vehicle will be very difficult to stop. You need to take the car to a VW dealer for service or to a competent brake specialist in your area to inspect the system and rectify the fault.

VW did a recall on some earlier year models for a leaking brake servo and I understand the problem was a faulty vacuum hose which would fail and leak. I am not aware of any recall for this item on later models like your 2004 vehicle.

All the best.

Car is jerking ? mostly while pressin on brake..is this the transmission? 2004 chevy malibu classic


Hello kelley_hornb: My name is Roger and I will help with your problem: If this occurs when you apply the brake pedal? I would look at the brakes. Should your rotors be warped you will have a pulsing feel in the brake pedal when stopping. The harder you push the brake pedal the faster the pulsing feeling.The transmission useually does not cause this feeling or problem. The next time you drive your car. Feel for the sensation when you slow down. As the car gets slower and you can safely let the car stopwith gentle pressure on the pedal. The car should stop with the same pulsing feeling as the car rolls to a stop.Or try putting the car in neutral at 10 mile an hour and gently step on the brake. If you feel the puling then the problem would be the brakes and not the transmission. In doing this you took the transmission out of the equassion. Should you need further help please just ask. Please rate the answer. This way I know it was helpful. Thank You for using Fix Ya. Roger

Brakes


sounds like your abs feature is in-operative(that's the one that won't allow the wheels to lock-up when the brake is applied in an emergency)the abs system should pulse your brakes during an emergency application of pressure on the pedal,i'd get to a dealer immediately (and i mean don't go anywhere else until this problem is corrected)
