Check your brake fluid level. Under the bonnet in a reservoir with a yellow cap, make sure the level is on or near the max mark. Let me know if its ok.

Replace the Rear Brake pads. I had the same problem upon inspection of the rear brake pads, they looked to have at least 50% left on them. I changed them and the problem was solved.

I have a 2002 Grand Cherokee, and the brake warning light comes on at ignition, and stays on. What could be causing this?


omg what country, and which lamp there is not just one lamp.
"brake indicator used for vehicles manufactured
for the United States consists of the word
"BRAKE" imprinted on a red lens"
and
The Rest-Of-World
(ROW) market version of this indicator has two
International Control and Display Symbol icons
imprinted on the red lens; one is the icon for "Brake
Failure", and the other is the icon for "Parking
Brake".

why not read the manual first, or is guessing how it works fun?

posted it like 300 times now.
again, on one RED BRAKE warning lamp. (not ABS)
WJ jeep 99-04
see brakes chapter 3 covers it all.
the diffr pressure valve sets the red brake light on

"The parking brake switch is in circuit with the red
warning lamp in the dash.
The switch will cause the
lamp to illuminate only when the parking brakes are
applied. If the lamp remains on after parking brake
release, the switch or wires are faulty.
If the red lamp comes on a fault has occurred in
the front or rear brake hydraulic system.
If the red warning lamp and yellow warning lamp
come on, the electronic brake distribution may be at
fault.
In most cases, the actual cause of an improperly
functioning parking brake (too loose/too tight/won't
hold), can be traced to a parking brake component."
so unplug it to see that its not CAUSE.



parting shot, i make sure all red lamp devices are unplugged
1 by 1 to know which one is tripping, the lamp.
then after bleeded, I step on the brake pedal real hard.
100lbs or more
and this will centralize the DIFF VALVE NOW>
if not the brakes have air in the system.
or the DIFF VALVE is seized.
they can stick so, learn the MONSTER FOOT brake test./
use max brake pedal pressure now.

there is a parking lamp too. that glows and will warn of low fluid levels.
are you working on the car with no scan tool?
is yes, then you miss out on all those brake error DTCs
dont you... and work totally blind

Hi, my brake lamp stays on after turning ignition on in honda accord 1988 carb despite all brake lamps are working fine no burnt one, I appreciate your help


Majdi, if you mean the brake warning light in the dash is on after starting your car, the light is telling you there is a fault/problem with the braking system. You should not continue to drive if the brake warning light is on, as your brakes could fail. You will have to have a good shop check your brakes and diagnose problem and estimate repair. Check the attached links,instruction and guides, Good luck

2002 Mercury Mountaineer stuck in park. What can I short to get it moving?


Vehicle came in for other problems but now the transmission will not shift out of park. Tests/Procedures: 1. Check the operation of the stop lamps. When the pedal is touched the stop lamps must come on. If not, go to the brake lamp switch and check for B+ on the Light Green/Red wire. It comes from a 15A fuse #F2.23 in the inside fuse panel.

2. If OK, push on the brake pedal and check the Light Green wire for B+. If not OK, replace the brake lamp switch. Potential Causes: Brake Lamp Switch
Harness
I had this problem with a Sable about your year model. Try turning the key slightly forward, but not all the way on. The first key position before turning the vehicle on will sometimes release the shifter and allow you to drive the vehicle. There have also been several problems with the cruise control pressure switch located on the end of your brake master cylinder. This sometimes shorts out and blows a 5amp fuse located on your inside fuse box. Just a few items to hopefully get you going.. Best of Luck.

Brake warning lamp on steady only when engine running. Brake fluid level is ok. General brake operation is normal. When park brake set, brake warning lamp is brighter. Is it possible that the rear brake...


No.
It might be in the switch for the parking brake. Try to release it a little more with your hands. It's either in the parking brake system or the regular brake system. Anything ABS has it's own warning light. Have it checked by a tech; it's a safety item, ok?

Check Data Communication Link (DCL)


Look for a missing ground in the circuit. Almost sounds like your missing ground is being sought through other accessories. You will need a ground/power test light - This type lights Green for ground/and Red for power to find the problem.

BRAKE light comes on occasionally - parking brake not engaged.


check your brake fluid it is more then likely low.You might need brakes as when they wear they take up brake fluid as the piston extends to make up for the worn pad material.
