We recommend the mid 80's S10/Blazer booster for low vacuum apps. Any 64-80 master can use it, along with later masters too.
Chad, yes my booster etc is on the firewall. The firewall has a large piece of 3/16-1/4 plate welded to the inside to strengthen it. The booster pic that scarebird posted looks the same as mine.
small up-date... Called Master Power 4 times Friday afternoon, its now Wednesday night still no return phone call from their tech line thats so busy you have to leave a message and wait for a call back. At this point I will not buy anything else from them, and I certainly won't recommend them in the future.
I bought a front brake system from them. Customer service sucks. Technical support sucks. Power booster sucks. Master cylinder sucks. Copper washers were to thin to seal. They'll run you around in circles over vacuum. I had the old (1964) booster rebuilt. Bought a master cylinder from Auto Zone. System works like a champ. I might buy spindles from them again. Otherwise, Master Power Brakes Suck!
Progress update... Got a return call from Master Power VP thursday afternoon, another call on friday to set up a return for the master cylinder that I have now. Their gonna send me another master, I send the bad master cyl. back to them. All I have to pay is the shipping back to them! I guess they're gonna make it right with me yet. I'll let 'ya know how much better the new master cyl. works.
Ok. Its been quite a while since my problems started with the brake system. I just wanted to let everybody know that the guys at Master Power did come through for me. They sent me a replacement Master Cylinder, I just had to pay for the return shipping. Unfortunatly the problem was still there, until I talked to Rob and Deb (kustomlincolnlady) while myself and the car were at Autorama. Seems that the problem was with the orig. factory set-up. The engineers had installed "overide" levers in case the power booster went out while you were driving. On the advise from Rob I removed all the extra stuff and now just simply have a swing arm that is attached to a push rod. I am still unable to drive the car due to the fact that I need a throttle cable and a shift cable, but I have much more pedal travel and the brakes feel like they will work fine. Master Power brakes don't suck! The engineers at Lincoln thought they had a good idea, but in real life it just did not work. I will recommend Master Power to anybody that asks.
Rob helps you so everythings fine with MPB! ??? Why did you have to pay for shipping back the wrong part? Their parts and service still suck.
i had to install there (bolt in ) kit in a 32 plymouth for a customer.. what a friggin disaster! ended up having to cut the pedel in 3 places, and buy another master coz the one they sent was junk. everything about it was wrong, and couldnt get a human on the phone for 3 days... what an enormous waste of my time, that i didnt feel rite charging the customer for, so i lost my shirt on it... they suck!!!!!!!!!!
