Worn e-brake linings or e-brake linings and cables are out of adjustment.
No Good, Excessive brake travel!
Answer 1 - Excessive Pressure Required to Activate Brake LightsAlthough I am not familiar with your vehicle, I suspect that the cause for the symptom you describe is that the brake light switch position is out of adjustment.
10 milimeter socket adjustment screw located at emergency brake pedal , look for adjustment nut to the left of emergency brake pedal .................................................................................................................................. before you adjust there, you may want to make sure your brake shoes are adjusted up (assuming they are drum) properly, which would likely take care of the problem, because if there is excessive space between the shoes and surface of drum, you will be asking the cable to compensate for this problem, which would cause it to travel more than it should. Also, excessive space between shoes and drums will also cause your hydraulic system brake pedal to go down farther than it should, which will not be cured by adjusting at the pedal or handle
Probably the brake booster going bad.
check your brake fluid. you probably ran it low and now there is air in the system. there may even be a leak. you will need to top off the reservoir and then bleed the brakes. look for brake fluid leaking around the inside of the wheels to try to locate the leak.
The brake pedal has nothing to do with it. If air is in the system then bleed the brakes.
brake switch located on the top of the brake pedal
Hardness in the brake pedal can because by low brake fluid. Air in the brake lines can also cause the pedal to push hard.
Check around brake pedal for something rubbing. If OK, I'd look into the master cylinder.
pedal travel is dependent on several things. first,check brake fluid level. then,i would remove the wheels and drums and look at the brake shoes. if they are worn,replace. also ched adjustment of emergency brake. low e brake can cause low pedal and is also an indicator of worn rear shoes. after replacing shoes,orif no worn shoes are found,wheel cylinders may need bleeding. bleed right rear,front left,left rear and right front in that order. do NOT adjust pedal travel at master cylinder since this may cause brake binding due to fluid return restrictions.
Check the switch adjustment on the brake pedal arm.
