Patcon Posted June 8, 2019 Share #13 Posted June 8, 2019 When one of the brake circuits (front or back) fails, there is a piston in there that slides and illuminates the brake light in the speedometer Link to comment Share on other sites More sharing options...
Zed Head Posted June 8, 2019 Share #14 Posted June 8, 2019 The fluid passes right through it. Front and back are separated. The piston in the middle moves if there's a pressure differential. 1 Link to comment Share on other sites More sharing options...

bingo Posted July 3, 2019 Author Share #16 Posted July 3, 2019 Just as a follow up, new fluid and the heat shield did the trick. Brakes worked perfectly last track day. 1 Link to comment Share on other sites More sharing options...
wheee! Posted July 3, 2019 Share #17 Posted July 3, 2019 When one of the brake circuits (front or back) fails, there is a piston in there that slides and illuminates the brake light in the speedometerThe brakes need to be “pumped” to actuate the piston in this device. The piston then blocks the defective line and shuttles all fluid to the working brakes. Quite ingenious really. ... as long as you remember to pump the brakes when they fail! 1 Link to comment Share on other sites More sharing options...
