IF you have DOT 3 fluid, check the color of your hydraulic fluid...it could be boiling and getting burned - color will quickly get darker..some do that for some reason which is why lots of folks have switched from DOT 3 to DOT 4 or DOT 5.1 . These have higher boiling temps and compensate for earlier boiling temps of the DOT 3, which can cause what you describe. Mine did the same when hot, especially in slow traffic etc, and after switching fluids my problem went away. DOT 5 is not universally recommended as it is not compatable to DOT 3 whereas DOT 4 and DOT 5.1 should be ok. You should still purge the entire system though for safety sake.

IF you do not have DOT 3, then disregard the above...and I can't help ya. Bill.
