Co-worker had me take a look at her 2006 Sedona w/64k, the original complaint was front brake noise.
The front pads had 5mm left but whoever did the job last at the dealer, did not reinstall the shim kit. (Not sure why it took so long to make noise, perhaps the noise had gotten worse lately?) I noticed the brake fluid was getting dark so I advised and got approval for a brake flush. I used the Motive 1117 cap and 15-20 psi to do the flush in the LF, RR, RF, LR sequence (had a brain hiccup and realized that LF, RR, LR, RF is the correct one - but brakes work great so no harm done).
The fluid in the front calipers was moderately dark, but the fluid from both rear calipers was the grey/black and had the viscosity of 10w-40 motor oil. I would guess that over 8 ounces of this nasty stuff came out from each of the rear calipers. The thick stuff took a long time to come out, but the fresh fluid escaped at a much quicker rate thereafter.
Overall, I flushed through two quarts of BrakeBest DOT4 fluid. There was no complaint of a low pedal before I worked on the car, and the pedal felt pretty good on the test drive after.
My question is....how in the world can brake fluid turn into thick, grey/dark sludge? This car does not have a lot of miles on it at all.
Ideas?
