Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / March 200893 Grand Voyager loss of brakes
Started my van this morning and the brake and ABS light came on. Brake pedal went almost to the floor. For the last couple of days, I've noticed a buzzing everytime I step on the brakes and the ABS light would flicker. Now it has almost no brakes and the buzzing is almost constant. There are no visible leaks on the driveway. Any ideas? > Started my van this morning and the brake and ABS light came on. Brake > pedal went almost to the floor.

If there are no leaks the problem is most likely a bad master cylinder. > Started my van this morning and the brake and ABS light came on. Brake > pedal went almost to the floor.

What I'm wondering is if the buzzing (sounds like an air compressor) is related. I have heard about some kind of electric brake pump on these that is notorious for failing. The buzz was only when I started the van, now it is constant. >> Check the brake fluid level.

There was a recall and/or TSB for that system, but that was already a number of years ago. Have a dealer run the VIN of your van to see if its had all brake-related recalls performed. I don't remember when they quit using that system, but I think it was after 93. It was only used in the vans, my wife's 93 LH car has a completely different system. The Bendix system used in early Chrysler minivans sucked for many reasons, not the least of which was that it failed a lot. But IMO the most egregious of its flaws was that it HAD to be working for the brakes to work normally. Virtually all other ABS systems (and all the good ones...) revert to a perfectly normal non-ABS system if the ABS function dies. > Started my van this morning and the brake and ABS light came on.

John, As others have said, you probably have the infamous Bendix 10 ABS system that they had so many problems with. What happens is, the seals go bad and the accumulator will no longer hold pressure. The pump will run continuously trying to build pressure and will eventually fail. That's the buzzing noise you hear. There was a recall (Chrysler recall 685) back in 1996. Do a search of Usenet groups in the archive, and search "Bendix 10 ABS system" for all the discussion thru the years. You can also go to: http://www-odi.nhtsa.dot.gov/cars/problems/recalls/recallsearch.cfm Search on NHTSA Campaign No. 96V099000 Click on "document search" Click on RC-96V099-NN.pdf, and read all the documents for a complete explanation of the problem, and the lifetime warranty on the pump/motor and piston seal. But that doesn't mean that your repairs will be covered free, only those lifetime parts. Anything else in need of replacement will be additional cost.
