elbago Posted February 17, 2012 Report Share Posted February 17, 2012 Having problems finding ABS Powermaster parts for my baby. In particular, a relay the Helm Manual calls an ABS Master Relay. Unfortunately no part number is given. The parts books at the local Pontiac dealers in the area do not include the Powermaster braking system. Looking at the switch, it is made by Denso but the part numbers are not legible. I am an office geek type, so if you guys could point me in the right direction, I would appreciate the help. The relay (located below the powermaster unit) had been sticking after the car was turned off. I had to tap on the relay to make it stop clicking. On the way to work this morning, my brakes went out. Plenty of fluid in the resevoir, no leaks. Any ideas? Quote Link to comment Share on other sites More sharing options...
White93z34 Posted February 21, 2012 Report Share Posted February 21, 2012 Where to start....What is the BRAKE and ANTI-LOCK lamps doing on your dashboard now? as for the relay, try calling SIA Electronics - (800) 737-0915 ask for Kevin, they support these units still. How new is your accumulator? Quote Link to comment Share on other sites More sharing options...
elbago Posted February 21, 2012 Author Report Share Posted February 21, 2012 The dash BRAKE light goes out when the parking brake is released and stays out. "Check ABS" on the console display has been lit since 2002 when I purchased my baby. The accumulator is at least 10 years old and may be original equipment.

White93z34 Posted February 26, 2012 Report Share Posted February 26, 2012 Did you try calling SIA electronics? I *may* have a spare one sitting around but I have absolutely no way of guaranteeing if it is any good or not. Quote Link to comment Share on other sites More sharing options...
elbago Posted February 27, 2012 Author Report Share Posted February 27, 2012 No, I have not called SIA yet. I do not have a part number for the relay. The exterior of the relay is worn. The relay appears to have been manufactured by Denso and the part number appears to be 055700-8420. I did not want to bother Kevin without a semi-warm and fuzzy that I had a correct part number.

elbago Posted February 27, 2012 Author Report Share Posted February 27, 2012 I called Kevin. He said he did not have the relay and pointed me to ebay. I did not find anything on ebay. Please tell me more about the relay you may have. Quote Link to comment Share on other sites More sharing options...
