I have a 2003 W20 M/H. In Nov '06 I experienced what I thought was caliper hangup on one wheel. The local WCC tech checked callipers and found no hangup. His diagnosis was water absorption in the brake fluid so he flushed the system. Yesterday I was preparing for a trip and exerienced another overheat on one possibly two wheels. Raised wheels on the leveling jacks and all rotated freely. Made another short drive with minimal braking with no apparent problem. Checked fluid in master cylinder and it again appears to be the consistency of jelly. Any suggestion why this would occur such a short time (7 months ) after a system flush?

I hope you can come back often to visit and please feel free to post at your leisure.

The jelly like substance in yours and my master cylinder is a by-product of the chemical reaction between the preservative used on the brake hardware and the brake fluid. I am told by Workhorse that the floating jelly is only located as a skim coat in the master cylinder and is innocuous and does not present any type of issue that would impact the operation of the braking system.

After my post this A.M., I used a plastic tube to get a sample of fluid deeper in the master cylinder tank and yes as you said, the jelly is only a surface condition. The deeper fluid is quite liquid and clear. Many thanks for your comment.

As a newby to this forum, I want to thank all who participate for a great service to the WCC community. I plan to visit often.
