Frequently Asked Brake Questions

Thanks to www.reatta.net for the following questions and answers.

1 - My Yellow, Antilock Brake Light seems to have a mind of its own. It is intermittently on?

Answer: An intermittent yellow light is usually caused by a failing Main Relay, unless the light only comes on when the Brakes are applied. If you have, in the past, had an intermittent Yellow light that is now, "On", all the time, the Main Relay has probably completely failed. You can test the Main Relay by switching it and the Pump Relay or simply replace it. (See Relays and Diagrams)

2 - My Yellow, Antilock Light comes on when I apply the Brakes?

Answer: You probably have a failed Accumulator, especially if the Red Light follows shortly. Take the Brake Tests in Troubleshooting.

3 - My Yellow, Antilock Brake Light never goes off?

Answer: The Main Relay may have failed but before replacing, read the codes at the ALDL. Instructions are in Troubleshooting Link and the Manual. Retrieval of the codes is simple, fast and requires only a paper clip or a short wire.

4 - My Red Light comes on when I apply the Brakes?

Answer: Indicates Low Brake Pressure. DANGEROUS. Take the Brakes Tests and park the car until the problem is resolved.

5 - My car pulls to one side when I apply the Brakes?

Answer: Cause could be a pinched line, a malfunctioning caliper, a seal failure in the Master Cylinder or a malfunction of a Servo Valve in the Valve Block. All of these possible causes are serious! Take the Brake Tests, retrieve ALDL codes, then have the car diagnosed by a qualified mechanic.

6 - My Brake Pedal goes to the floor when I apply the brakes?

Answer: This is a" no drive" situation! Possible causes, excessive air in the system, internal leaks, external leaks. It may be possible to floor the pedal, immediately after starting the engine, before lights are out, while sitting in the driveway but once underway, this, "should not happen."

7 - My Brakes feel spongy and soft?
