Not usually. It is possible for the mater cylinder get suck in the apply position, but the brake pedal would not return to the up position after stopping. A more common problem for the brakes to be stuck applied is a locked wheel cylinder or brake caliper, or a jambed parking brake. These issues will be at one or more of the wheels, so check there if your brake pedal is at normal height.

Why does my 92 Corvette parking brake light stay on?

Check the level of brake fluid in the master cylinder reservoir. If it is low that will illuminate the brake light also. If it is low on brake fluid it's time to have the brakes serviced.

It would be helpful to know: What vehicle you are working on. The condition of the rear brakes, and were they also bled. Does the brake fluid level stay full, if no then there may be a brake fluid leak.

Why would you brake light and ABS light stay lit on the dash when the brakes are new?

The abs light is a separate system from the brakes.. I know that sounds funny but the abs system is after the break system. Your brakes will still work if the abs is inop. The brake light is usually a fluid level indicator in the master cylinder, not a light to tell you to replace the pads or shoes. I would look for a fluid leak or a problem with the parking brake.


1989 ford f150 rear brakes lock up when you barley touch the brake pedal what would cause this and what steps should you take first to fix the problem?

worn out brakes will cause this allowing the pistons not to return to correct adjustment.loose parts inside brake drum from will also cause this so if you inspect rear brakes with brake drum removed and this is not the problem, your master cylander is bad and not allowing fluid to return to resevoirr, therefor still keeping brakes expanded if this is the problem the it will get worse each time u use brakesuntill they stay locked up and you cannot move vehicle get brakes checked yesterday


After replacing the master cylinder on your 1996 Ford Aerostar the warning lights on the dash stay lit what is the problem?

Your brakes need bleeding. And if you have antilock brakes, you should take it to a shop to bleed them. It takes special tools to bleed antilock brakes. If you have regular brakes you can bleed them yourself. Could go into further detail but would take too long to explain. Refer to a repair manual. Note: bleeding antilock brakes without first disconnecting the sensor will damage the sensor and the antilock function will no longer work (learned the hard way, unfortunately).


What causes front disc brakes to stay engaged when warm and disengage when they cool down?

The next time the brakes are stuck engaged, try opening a bleeder in one of the calipers to see if the pressure releases or not. If the pressure releases I would suspect a faulty master cylinder. If only one caliper is stuck, it could be a collapsed brake hose, stuck slider pins or a stuck caliper piston.


What would cause the brake light to stay on in a 2001 Honda Accourd even if the emergency brake is off?

Something needs to be looked at. My daughter had the same thing then lost her brakes completely. Found the brake line broke ended up replacing all four rotors and brake pads. They had to remove the gas tank to replace the line and also replaced master cylinder. $1900.00 at a Honda dealership in Pittsburgh PA.
