truthfully we dont, the brake light came on for a few minutes then went off---so we were going to check the fluid level before checking the brakes, but just couldnt find where to even check the fluid ----the book said to check the master cyl. but didnt tell where it was--lol
the brakes were working fine--just the light came on---we got this camper in December and only drove it from NC to SC so far--not put much time with it because of work--going to have fun this summer though.
