Why do I have intermittent hard brake pedal?
Hard Brake Pedal Intermittent – Vacuum Pressure Vacuum – or really lack of vacuum pressure – is the most common cause of a hard brake pedal, and therefore the first thing to look at when a hard pedal is present. Any brake booster (whether from Master Power or any other supplier) needs a vacuum source to operate.
Where are the brake connectors on a Honda Accord?
Spread a plastic sheet under your car to catch the leaking brake fluid. Locate the two electrical connectors on the master cylinder. From the driver’s point of view, they are located to the left and on the back of the master cylinder. Push in the tabs of each connector and pull them away from the master cylinder.
How to diagnose hard brake pedal master power brakes?
A) With the engine not running, press and depress the brake pedal several times to remove any vacuum from inside the booster. B) On the last push of the brake pedal, hold moderate pressure on the brake pedal. Don’t push like you are panic stopping, but simply hold pressure like you are sitting at a red light.
What should I do if my brake pedal goes to the floor?
You should hear each connector click into place once you have correctly attached them. Turn on your car and step on the brake pedal. It should no longer press down to the floor and should also feel tight. If it is still hitting the floor, check to see that all of your connections are in tact and if not, secure them in place.

Can a unresponsive brake pedal stop a car?
This is an obvious problem, as an unresponsive brake pedal will not stop a vehicle, or will not be able to do so in an adequately safe manner. In most cases, this will happen slowly, over time.
A) With the engine not running, press and depress the brake pedal several times to remove any vacuum from inside the booster. B) On the last push of the brake pedal, hold moderate pressure on the brake pedal. Don’t push like you are panic stopping, but simply hold pressure like you are sitting at a red light.
Is the grinding / rubbing noise intermittent on braking-brakes?
Is the noise/pedal pulse only there when braking. More light braking but coming to a complete stop at junctions. The front discs were quiet corroded on the inner pad was making a groove in the pads. Yes noise is only there when braking & coming to a stop at junctions/islands.
Why do the brake pads disconnect when braking?
The vibration at low braking force is also consistent with disks that are slightly off true, causing the pads to connect and disconnect repeatedly when braking slowly. When braking more strongly, caliper pressure will force the pads into continued contact with the disk, so vibrating much less if at all.
What causes a low brake pedal when replacing a master cylinder?
When replacing a brake master cylinder, we may need to adjust the push rod from the brake booster. This is easiest with the tool made for the purpose. Failure to properly adjust the push rod can result in a low pedal or brake lockup. Much more information and pictures are available in the Detailed Topic on Diagnosing Brake Lock Up.
Why does my brake pedal feel soft when I hit the brakes?
Issues such as air in the lines, failing calipers or wheel cylinders, or a weak flex line can feel soft when you hit the pedal. Your brake pedal should be firm and the brakes should feel solid and apply gradually. When the pedal is soft and spongy, your braking system is not functioning at 100%.
What should I do if my brake pedal is hard to push?
If the brake pedal is hard to push, the problem is most likely in the power assist mechanism. There are two types of power assists – vacuum and hydraulic. Most cars and trucks use a vacuum booster to provide braking assistance so that the driver doesn’t have to exert as much effort on the brake pedal.
What causes a high pitched whining noise when braking?
This shaking can also happen if the pads are warped, damaged, or excessively worn. If it’s your brake pads, you will likely hear a high pitched whining noise when braking. How To Fix: Replace your brake pads. Cost: Brake pads usually cost anywhere from $35 to $150 for a complete set for one axle.

What to do if your car’s soft pedal stops working?
If you hit the brakes hard (like a sharp initial tap on the pedal) they would work fine, but if you eased onto them they went right to the floor. This was, of course, an intermediate step towards brake failure, so I suggest you park the car until the braking system is fixed. Vacuum booster needs replaced. Not too hard to do.
What happens when you press down on the gas pedal?
Engine response is inconsistent When you press down on the gas pedal, your engine should respond directly and instantly. However, when a problem with the APP sensor exists, the vehicle’s ability to consistently accelerate or decelerate as directed by the driver is reduced.
What causes the accelerator pedal to stop working?
The primary reason why this part fails is due to exposure to high heat, as it’s typically located on the floorboard next to the firewall of the vehicle, in very close proximity to the engine.
What happens when you depress the gas pedal?
I have a 2013 Hyundai Sonata automatic. 125,000 miles. While driving and depressing the gas pedal, acceleration stops. Pressing further on the gas pedal, noting happens.
Is there such thing as an intermittent soft brake pedal?
Intermittent problems can be really tough to diagnose. I believe it’s pretty much got to be the MC but I for one, hate throwing parts at a problem to try and fix it. Also, you’re thinking correctly, in that you couldn’t buy a car without power brakes these days. Please explain your logic behind both statements. Click to expand…

What should I do if my brake pedal is going to the floor?
:thumbsdown: This is colossally bad advice. If the brake pedal is intermittently going to the floor she should not drive the car at all until it is fixed. Try bleeding the brakes first and see if that cures the problem. I would also inspect every line to see if there are any leaks anywhere. The brake fluid is full to the brim?
