Hi i recently failed inspection because the e-brake in my 93 Celica doesn't work. I need to figure out why and fix it asap but I cant find my owners manual. It'd be helpful to see the mechanisms and understand how they function, maybe a diagram would be useful too....all of which i imagine are in the manual. How should i go about finding out what I need to know to fix this. Thanks for your time and input. K8

Go to the auto parts store and purchase a Haynes or Chiltons repair Manuel.They are around $25.They have wiring diagrams and pictures with step by step instructions.They cover just about every thing on your car.

your foot pedal is a hydraulic brake and is used constantly. the brake pads are on the outside of the rotar and in constant motion in and out which wears the seal inside the caliper causing it to leak.as for the emergency brake, it is a mechanical brake inside whats like a small drum on the inside of the rotor (back rotors only) the mechanical parts inside the drum will seize up because they are never used and are exposed to the elements everytime you drive. if you have the emergeny brake serviced and fixed and want to keep it in good working order you would need to start using it more often. as for the fuel presure loss could be another bad fuel pump or a restriction in the lines somewhere. maybe a malfunction fuel presure regulator. hard to say without looking at it
This means you have something worn out in the brakes. It is usually an accurate indicator. You could be low on Brake fluid, but then something is leaking and that is not good.
You need to check the Brake pads, Rotors, and take off the rear Rotors to check the Emergency brakes. Remember to clean the debris off all the sensors you see with Electrical wires on them. Remember to tell the Brake place if you have someone work on it, that you want the Emergency brakes checked.
I have had some clients go to both a Dealer and a Brake place and both places failed to find the bad Emergency brakes.
First have the vehicle's braking system inspected for internal and external leaks ASAP. I don't doubt that fluid level is probably low, but topping it off is not the answer. If no leaks were found then wiring to hand/foot emergency is loose and grounding out.
Assuming the wiring to the brake lights is serviceable, you will find that the brake light switch, which is activated by the brake pedal for the brake lights, will have failed and will need to be replaced.
Just ensure you first replace the fuse and both brake light bulbs as an initial step and then re-check to ensure you still have no lights.
HI. this will occur if there is an issue that has been discovered by the on-board CPU. The light will illuminate when there is an apparent malfunction within the ABS sensor assembly. These sensors are located on each axle/rotor assembly. The correct action will be to have these speed sensors inspected, if possible. This could be a simple loose connection, or a failed sensor circuit as well.
