brake pedal

Hi there. It sounds to me that you have warped brake rotors. This problem occurs when your brakes heat up to a point where the pressure exerted from the tightened lug nuts bend your rotors. When you press your brakes,...

Your engine has direct fuel injection. Over time, the intake valves can suffer from carbon build up because fuel is not being washed over them. Always use top tier gasoline even if you use Regular and not Premium. You can...

I believe you may have a problem with your master cylinder. I would suggest first having the brake fluid flushed if it is dark. If that doesn't fix it then most likely the master cylinder is bad. I would have...

If this is not related to any vacuum leaks, the next place to check would be the brake booster itself (https://www.yourmechanic.com/services/hydraulic-brake-booster-replacement). As you press the brake pedal down, a shaft inside the brake booster moves forward into a diaphragm, which...

I strongly recommend this car not be driven before this problem is addressed as a safety concern. If the pedal goes down to the floor it means one of two things, either air has become trapped in the sealed system...

A sinking pedal is often a sign that there is a leak somewhere in the brake's hydraulic system. Sometimes a problem of this nature may render a vehicle unsafe to drive, as braking systems relies on sealed pressure to operate....

The noise is coming from your brake booster has a vacuum leak and will need to be replaced. This is why your engine runs rough when you press the brakes.

The brake pedal is working to stop the vehicle, but there may be air in the controller unit causing the ABS brakes to not function. I recommend bleeding the brake system from the farthest location from the master cylinder to...

Hi there. There is a lever that is attached to the brake pedal that has an adjustment screw. The screw was pushed out making the brake pedal higher than normal. Turn the screw inward and the pedal height should drop....

Hello, thank you for writing in. There are pedal extensions on the market you can purchase to raise the pedal up higher. Typically there are other ways to adjust the pedals as well (typically for performance or handicap purposes). These...

The brake master cylinder is most likely leaking internally; it needs to be tested, replaced then bled out of air. If the system fluid is not low, then this is the most likely cause. I recommend that you have a...

I believe you may have a problem with your master cylinder. I would suggest first having the brake fluid flushed if it is dark. If that doesn't fix it then most likely the master cylinder is bad. I would have...

Hi there. The first thing that needs to be determined is if there is a failure of a line or brake component, such as, a brake hose, caliper, or wheel cylinder. The brake fluid level needs to be checked to...

The brake pedal pushes on a rod that goes to the master brake cylinder. This, in turn, sends brake fluid to all of the wheels through the lines to the brakes at each wheel. If your pedal is going to...

The pedal going down to the floor usually indicates a loss of hydraulic pressure. Possible causes include a leaking brake hose, a dysfunctional caliper, or a wheel cylinder. Also a master cylinder leaking either externally or internally will cause the...

With the vehicle off, pump the brake pedal until all of the assist has been diminished. This will empty the brake booster. Upon pumping, the pedal should become more and more stiff until it feels like you are almost stepping...

If the brake system was working before and now the brake pedal is hard and the front calipers are not moving, then the brake booster has failed (which is the hissing sound that you are hearing) and there seems to...

Hi there. First check the brake fluid and make sure that it's full and clean. If the brake fluid is black in color and is the original brake fluid in the vehicle, I recommend flushing the brake fluid to remove...

Hi - from your description of symptoms, it sounds like the brake booster has an air leak (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-hydraulic-brake-booster), or possibly the hose to the brake booster has a leak. The brake booster uses engine vacuum for braking assist. If the...

The brake pedal should stay up hard when you have the engine off. As long as you do not see any loss of fluid after system is bled out of any air in the system. You may need to have...
