If you have not replaced any brake lines or brake calipers, then It sounds like that the brake proportioning valve or the brake master cylinder if defective. If the the brake pedal goes to the floor, the master cylinder is at fault. If not, the proportion valve, which is part of the ABS valve body is defective. Have your local garage check these two components for possible problems.

Brake fluid leaking


Look at the insides of the wheels from under the car and look for a wet wheel. Check around the rear of the brake master cylinder for signs of leakage. Sometimes the fluid will leak from the brake master cylinder into the brake vacuum booster. You would need to remove the master and check for fluid in the booster.

Locking brake on the rear passenger side!


Its probably the rubber hose that goes between the metal break line and the caliper. That hose is like a 2 way valve that lets fluid into the caliper when brakes are applied and lets fluid back out when brakes are released. These hoses deteriorate and stop letting fluid back out causing the brake to stay tight against rotor.

Hi, two months ago low brake fluid indicator came on, brake fluid was added. This morning low brake fluid warning came on. I must have a leak. Front brake pads & rotors replaced 10 months ago.


Take it to a shop which has a lift, like an oil change or muffler shop, have them put on the lift. The leak will be apparent as it will be a wet recent stain. Then you will know if you are looking at a brake line fix, a leaking master or slave cylinder.

Do not blame the guy who did the pads 10 months ago, anything he did wrong would be immediately apparent and would not take 8 months to show.

Brake light on the instrumentation panel on my Toyota Sienna 2004 is "on". The "foot brake" is not engaged. What should I do?


If your brake system seems to be operating ok, then more than likely the system is low on fluid. As brake pads wear, this allows greater travel in the caliper and thus the caliper piston has to travel further to make the pads come into contact with the brake rotor, causing the fluid level to drop in the reservoir. Once the fluid level drops so far, the brake warning lamp will illuminate. When you check the fluid level, also inspect under the vehicle and around the brake lines for and sign of brake fluid leakage that could be causing you to lose fluid as well.

There are no brakes on my 1997 jeep cherokee the brakes go all the way to the floor already replaced the brake pads


Hi:
Your problem is related to the master cylinder, wheel cylinders, or the brake lines. First check the brake fluid level. Check the inside of all four wheels and look for signs of brake fluid leakage. If you don't see any leaks, and the brake fluid reservoir is full, then you most likely have a bad brake master cylinder. If you do find a leak at any wheel, and fluid level is down, then concentrate your repair efforts in the area of the leak.

Brake light comes on and off and it makes a dinging noise while on very annoying


Put some brake fluid in your brake reservoir. (DOT 3 Fluid) Your brake shoes and pads have worn more than 50 %. Due to the wear the reservoir is natrually drained to make up for the wheel cylinders having to extend further to get the same braking action.
Also take a look around the inside of all of your axles for signs of leakage. A leaking wheel cylinder will also cause brake system fluid loss.
