Hello,
I have posted about this before and had hoped I had been able to fix my problem with soft, nearly ineffective brakes.
Over the last year, and especially during cold weather or when driving in mountainous terrain or going up significant amounts of elevation, the brakes on my 2006 T1N 3500 become very soft, a significant difference from how they felt when I bought the van 2 years ago.
The rear brakes were professionally serviced 15K miles/16 months ago, and I have only had about 20K mi since I bought the van, which now has 120K miles, and the brake rotors and pads are in good condition..
During the last year, I replaced the master brake cylinder, and have pressure flushed the brakes many, many times, which usually results in getting a few air bubbles out especially from the left rear caliper, and in turn firmer a firmer brake pedal for 2-3 days, which then becomes weak and very spongy depending on how much elevation change or driving I do.
There is no evidence of any brake fluid leaking from any of the calipers and the brake fluid level within the reservoir is always unchanged.
I have tried to activate the ABS shortly before flushing the brakes without much improvement in the overall outcome, the brakes still get soft again over time.
I have read that in time the brushes within the ABS system become worn out.
Is it possible that this is the problem?
I have considered replacing the brake caliper, but I am not sure if that is the problem...
I would really appreciate some thoughts or suggestions on anything I may be missing or should try.
Thank you soooooo much
Doug
