Re: Vehicle shuts off after hitting brakes
Press the brake pedal with the engine idling, do you hear any hissing? if so it is a leaky brake booster, the vacuum leak will cause a stall, another issue with this car is sludge in the throttle valve and idle speed control air-bypass valve, clean them both with carb spray with the engine running, use about 1/2 the can, hold the idle high or the engine will stall, then disconnect the battery for five minutes, reconnect and drive a few miles, if the stall is sludge related then this should correct the issue.

Hard brake pedal when applied with the engine running. A quick test for the vacuum assist booster is to shut off engine, pump brake pedal 3 or 4 times and hold on the last pump, start engine and see if pedal drops a bit....if you detect a problem with booster you should check for adequate engine vacuum supply to booster when idling . You can sometime hear a hissing or air leaking when applying brake pedal with engine running if booster is defective
SEQUENCE ACTIVATED BY THE PARKING BRAKE . 1. While engine is running (key in ignition switch), apply the brakes and hold the pedal down. 2. Move gearshift lever to neutral. 3. Apply the parking brake Once Twice Note: The system can be set - at time of installation - to require that the parking brake be applied once or twice. If set for two actuations, pause one second between the two. 4. Remove key from ignition (the system keeps the engine running). 5. Exit the vehicle. 6. Within 60 seconds, close all doors. 7. The system will stop the engine and blink the parking brakes once to confirm the sequence is valid (vehicle is ready for a remote start command). SEQUENCE ACTIVATED BY THE REMOTE CONTROL 1. While engine is running (key in ignition switch), apply the brakes and hold the pedal down. 2. Move gearshift lever to neutral. 3. Apply parking brake. 4. Send the start command (Model 801 & 2101 - Model 903 ). 5. Remove key from ignition (the system keeps the engine running). 6. Exit the vehicle. 7. Using the remote, send the STOP command. The system will stop the engine and parking lights will blink once to confirm that the sequence is valid (vehicle is ready for a remote start command). http://www.astrostart.com/Support/Guides.aspx
Sounds like a wire was broken by the belt somehow. You have some fuseable links and large fuses that power the components on the car. I would look around for a loose wire close to the belt side of the engine, and check the fuses for power.
Hello, Look under the dash at the top of your Brake Pedal lever. There is a switch there that often gets hit by the shoe of the Driver. If this switch is cracked the internal parts can short out.
The switch is part of the Interlock system for the Starter and also goes with the Gearshift selector. I imagine the short can do other things if the car is in gear as opposed to its normal function in the Park position.
Although the other connections at the Firewall or "Bulkhead" may cause problems, I rule this out because any Vibration would make such a connection cut-out without applying the Brakes. The switch I mentioned is directly affected by braking and is a better candidate for your problem. Please let me know what you found.
hard brake pedal and the engine is idling rough usually indicates the power brake booster has gone bad. the booster has vacuum going to it from the engine so if the diaphragm in the booster starts leaking then it affects engine performance.
either replace brake light switch or check on the brake pedal arm for a 1/2 diameter blue rubber brake light switch bumper pad. The brake switch is normally closed which means when you push the on brake pedal the switch makes and power is applied through the switch to the lights. When the brake pedal is released the switch actuator strikes the rubber bumper and opens the switch contacts. If the bumper is missing the switch will not open to break the power circuit to the lights.
The cables for emergency brake go under the car and being that old , the cables are probably rusted..The problem is if you apply the emergency brake it probably wont release.Either get new cables ,or learn to live without one
