You have lost pressure in your braking system.

Begin by checking for leaks around the car to see if you are losing brake fluid. Check the reservoir to make sure the fluid isn't low.

If you don't see any fluid visibly leaking anywhere (including the inside of the engine bay) and the fluid is at the appropriate level in the reservoir, you most likely have a bad master cylinder.

DO NOT continue to drive when you have a bad master cylinder!!!

I don't have the specs for your particular model, but some cars will have a slave cylinder next to the master, so that when the pistons inside the master fail to create pressure, the slave can act as a backup and continue to help supply fluid under pressure to at least two wheels. You already lost half your braking power and continuing to drive the vehicle could result in total failure of the braking system!

You will need to take it in to get it repaired, unless your handy and can do it yourself.

Either fluid level is low or you need to check the sensor located in the master cylinder. Master cylinder can also be bad.

How do i fix the button on my shifter for a 2000 firebird?


if it does not push down, then you need to change the interlock solenoid. First hit the brakes and make sure the lights work, because the brake light switch (at the top of the brake pedal) is what sends power to the interlock solenoid on the shifter.

What are the proper steps to bleeding your brakes on a 1990 vw golf deisel


For left hand drive vehicles: (If the car does not have ABS system you do not need any diagnostic equipment!)

IMPORTANT NOTE: You need using diagnostic equipment connected to the data link connector of the car in order to bleed the ABS block. Follow instructions by scantool equipment for bleeding the ABS block.


1. This bleeding procedure requires two people. Remove the brake system reservoir cap, and fill up with new brake fluid until "MAX" level is reached.
2. Lift the car, or use a channel for access under vehicle.
3. Put the gearbox in "N" - Neutral position, or in "P" - Parking position for automatic transmission.
4. Start the engine and push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor.
5. Begin with the rear right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
6. Repeat steps no.#4 and no.#5 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

7. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
8. Continue with the rear left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
9. Repeat steps no.#7 and no.#8 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

10. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
11. Continue with the front right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
12. Repeat steps no.#10 and no.#11 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

13. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
14. Continue with the front left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
15. Repeat steps no.#13 and no.#14 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.
16. Now the brakes are bleeded. Check the brake fluid level in the reservoir. Fill up with new brake fluid until "MAX" level is reached. Put back the brake reservoir cap.
17. Test the car brake system. The brake pedal movement no more than 1/3 of total stroke until the floor, when brake pedal is applied. Maximum admissible is 1/2 of total stroke.

When you push the brake pedal do the rear brake lights come on?
Check that next time it does not start.
You may need a simple brake light switch adjustment.

There may be air in the lines. Bleed all your brakes starting at the farthest wheel from the resevoir, and finishing at the closest one. Try the pedal after its bled. If the pedal still feels soft or travels to the floor there may be a pinhole leak that may be spraying on the underbody of the car, or the seals in the master cylinder are gone filling the vacuum booster(if equipped). Air compresses more than oil so if bleeding works that may be the problem.

2000 firebird brake lights do not work


Is this a 1998 or 2000?
1) Unplug the Brake Light Bulbs and with a Voltmeter, check for voltage on both sides.
2) If you have voltage: change the bulbs and recheck operation.
3) If you do NOT have voltage: go under the dash on the drivers' side. Look up onto the arm of the Brake Pedal. There should be a switch behind the arm, On the switch should be a plunger. With a partner at the rear of the vehicle: Depress the plunger in, and have your partner check for Brake Lights.
4) If you now have Brake Lights: the plunger and/or switch can be adjusted. The Brake Arm when depressed, pushes-in the plunger activating the Brake Lights. Some Plungers can be unscrewed (counterclockwise) to shorten the gap to the Brake Arm,
5) If you still have NO Brake Lights: Twist the Switch/Plunger 1/3 to 1/4 turn, removing it off the support bracket. Unplug this Switch and again check for voltage.
6) If you have voltage: the Switch is bad and needs to be replaced.
7) If you still have NO voltage: Check the fuses.
Let me know if this helped, or if you have any additional information or questions. Feel free to contact me at FixYa.com!
