Works and has had very clean fluid and exercise and has grey switch. I pulled piston and it was in excellent shape. Was rebuilt when i got my car in 2011. If brakes pumped rapidly for 4-5 times, i got a light....i tried reading up in the sticky on PMsater's and could not decipher the run on sentences regarding brake light. My guess is its accumulator ball as i never have put one on. Put yours on and run. If you dont want it after install, pay shipping back and ill give a refund. $135 +ship/paypal.
thanks
