Excessive heat, typically generated by excessive braking, incorrectly adjusted components, or improperly fitted components, or, in the case of air brake systems, faulty quick release or relay valves, brake chambers, or slack adjusters.
Braking too hard and often, particularly with drum brakes.
Any time the brake pedal is hard to press then you need to check and see if the brake booster is functioning properly.
it is when the top and bottom fade away
Contaminated brake fluid, mostly from moisture. Brake system should be flushed every couple years but nobody does it. (myself included)
The part of the car that turns on the brake lights when you apply pressure to the brake pedal is called the brake switch. Releasing pressure from the pedal causes the brake switch to break its electrical contact, turning off the lights.
most likely a clog in the line or wheel cylinder or maybe a broke spring
Heat up the brake pads and cause brake fade.
Brake fade is the reduction in stopping power that can occur after repeated application of the brakes, especially in high load or high speed conditions. Brake fade is caused by a buildup of heat in the braking surfaces and the subsequent changes and reactions in the brake system components and can be experienced with both drum brakes and disk brakes. Brake fade occurs most often during high performance driving or when going down a long, steep hill.
The washing machine
Brake fade is caused by the brake pads overheating. If this happens all the time and not just during hard braking, then the pads are glazed over. You can lightly sand them to remove the glazing, or just replace the pads. Now if you are referring to brake pedal being soft, then you have air in the system. Bleed your brakes. Check your e-brake too......Many people leave it on and not realize it. Brake fade will manifest very quickly.
a wild panda tampering with your brakes
Worn brake shoes or pads. A leaking brake pipe. Low brake fluid. Air in the brake fluid pipe.
Light
possible air in the brake lines.
You will wear out the brakes prematurely and you may also overheat the brakes and experience brake fade (no or poor brakes).
Check the brake fluid level in reservoir.
causes the colors in the tattoo to fade
Brake fade. - You can avoid this by fitting ceramic pads or better quality shoes.
