I topped off the front brake master cylinder (2000 RT with ABS) yesterday, not looking to see what fluid is required. After coming back from a 100 mile ride I looked at the cover on the master cylinder and seen the system required DOT4. I topped it off with DOT3 (about1/2 of the reservoir). Is this going to be a BIG problem? Will the system need to be flushed? Can I do this or do I need to have the dealer do it?
