Help figuring out cause for a BRAKE warning light
When I purchased my 1986 Turbo Esprit HCi the BRAKE warning light on the dash was constantly on. I have been trying to figure out why. I assume it is warning me that the brake fluid is low. I made sure that the fluid reservoir is full of brake fluid. Next I tested the cap on top of the reservoir with the two connected wires to make sure the low fluid switch was working...it is. Just for good measure I replaced the cap to be sure the switch was ok. The BRAKE warning light is still on. Tonight while looking around for other possible problems I noted what I show it the two pictures attached. In the first picture Attached Image there is some sort of off-white plastic device that connects the bottom of the servo-brake booster. I noticed that the device has a nipple for a hose connection but there is no hose connected to to it (see arrow). Anyone know what the off-white plastic device is? Should the open nipple be connected to something? My next questions are about the second picture Attached Image...coming off the servo-brake booster is a black hose, I assume a vacuum hose, with an in-line tee connector. The smaller hose coming off the tee is capped and nothing is connected to it. It is possible that the nipple without anything connected to it and hose coming off the tee without anything connected to is might be related? My final question...any ideas on what I might check that would cause the BRAKE warning light to remain on? The brakes on the car seem to work just fine. HELP!
