Ok, I read just about everything I could find on powermaster brake boosters. But I don’t think it’s my powermaster.
Let me start by saying in the 31 years of owning my we4 I managed to keep my eyes open and I purchased 4 known working 3 or them I witnessed working with my own foot. 2 guys converted to vacuum brakes (Which I’ve always been strongly against doing, it’s just my preference to keep all my TRs powermaster). 1 guy was parting a rotted GN out and I bought it from him. And one I recently purchased on eBay for a steal and the seller is a know TR parts seller and guarantees it’s functional. When I get each unit I look it over for cracks or leaks. Then I ohm out the motor and brake switch. Then I gravity bleed the motor and leave a little bit if new fluid in the left side of the reservoir, cover it up, wrap it real good in plastic shrink wrap and store then on a shelf in my closet.
So my WE4 was stored in my sister’s garage in carle place NY from 1997-2018 because my mom was a big help in me buying this car 3 days after my 17th birthday right off the dealer lot. When she passed away unexpectedly back in 1997 I was too emotional and hurt to even look at the car because before she lent me the cash to buy the car I was very disrespectful to her and said shit I can’t ever take back. So I was too crushed to even look at the car. So my sister let me Store it in her garage for 21+ years until she retired and sold her house this year. When i Parked it there all I did was remove the battery and give it to my sister for other card to use. I never prepare the car for long storage. So she shipped it to me here in Florida. About two months ago when I got an FL completely different about it and have been breaking my neck to restore back to a museum quality show car. One of the problems was a very stiff pedal. No brake light (now here’s where it gets tricky). No oil light upon ignition, no volts light, no change from the alternator either. Now I know the volts dash lamp completes the charging circuit. So tomorrow I plan to remove the dash cluster and check all the lamps as well as the coooer connection that powers up the entire dashboard.
Ok back to my original powermaster. Upon removing it I noticed that the pedal was stiff because of the years of sitting with dirty brake fluid inside the master cylinder and some was leaking out the seal where the hole for the pedal pushrod sits and was all hard like dried epoxy. The resistance on the powermaster motor and brake switch all checked out good. So I replaced it with a known good one with a fairly new accumulator ball that was replaced approximately five months before the car was parated out. Ok so here are my issues. Now I know you guys know a hell of a lot more then I know about our cars so I come to y’all again asking for your help please. This powermaster is definitely a known working unit. But I cannot get her to function. I installed it perfectly. I gravity blead the motor and Accumulator ball side. The brakes slightly work if I press as hard as I can.
Here is what I got so far:’
1) no red brake lamp on the dashboard no matter how much I troubleshoot the brake switch pigtsil harness. I can’t get it to light up.
2) absolutely no power/voltage from the brake switch pig tail harness and it’s very clean.
3) standing 12 volts in one of the wires in the pig tail harness that’s going into the powermaster motor connection.
4) I read something about the emergency /parking break being released having something to do with the brake lamp red right. How can I bypass the switch? It’s kinda seized because it sat so long
5) Probably a relevant to my problem with the power master but I’m going to mention it anyway Oil idiot red lamp not lighting up. Please lmk if this has anything to do with the powermaster. Same with the red volts dash lamp. That bulb has to be replaced because my car isn’t charging because of that.
So the bottom line is since I started with my car again I haven’t hesrd the powermaster motor prime itself at all. Honestly guys /ladies I feel it’s not the powermaster and has something to do with the no red brake lamp on the dashboard. And the fact that there is no power coming from any of the 3 wires that connect to the brake pressure switch.
****I HAVE NEVER HEARD ANY POWERMASTER MOTOR OR RELAY SINCE I GOT MY CAR BACK****
I removed that one big metal fuse and temporarily replaced it with a 30 AMP plastic fuse with no change. Are there any other fuses to check? Is there an emergency brake switch that’s causing some kind of interference with this power master issue ? Also my brake pedal is sticking from age and it kept the rear brake lights on, so I disconnected two sets of wires coming from there. Could that have caused this problem? Other then that honestly guys I’m stumped. All I can say is I swear by these powermaster units. Especially the one I just installed. Oh and yes the grounding wire that goes into the harness on the side of the powermaster is connected to the chassis ground with a clean great connection. I read about thst in one of theses thread about failing powermaster units.
Thank You all for reading and have a blessed day
Any answers or input to any of the questions would be greatly appreciated !!!
