87' DL Wagon Brake question
Posted 05 March 2006 - 10:53 AM
I'm posting this for a relative who has an 87' DL Wagon (Carb'd, and runs like a champ). He found this forum and wanted to see if anyone here might know how to help with this problem.
The wagon's brake lines rotted and were repaired. The system has been completely bled and when the car is off there is plenty of pedal pressure. However when you start the car, the pedal pressure goes away and is very faint, the drivers side front and passenger side rear brakes seem to not work. The car isn't leaking any fluid. We are stumped.
Any ideas on how to troubleshoot this problem? Anyone else hit this issue before? Vacuum booster troubleshooting perhaps?
Thanks for your help

but you need to remember that the brake pedal will feel differently when the engine is running versus when the engine is off and you have no vacuum.
a bad booster is detected by hearing a vacuum leak under the dash particularly when you are apply the brakes while the engine is running and also when you apply the brakes while you are driving your brake pedal will be high and very hard to push with very little braking ability.
one other thing to is make sure your rear brakes are adjusted up properly, this will effect your brake pedal feel too.
