Brake system of '91 Imperial

[messedup-imperial]

Hi everyone, I"m Steve and brand new to this forum, and I am in desperate need of some advice and hlelp asap. Well i'll give you a lil bckground on the problem, I got the car from my uncle for 150, well my dad did but said i could buy it if i can get it fixed, The master cylinder went on it, other than that it is an emmaculent sunday driver. From what I understand this is the only year that Chrysler had the odd idea of combining the brakes and power steering system, there for making it impossbile to track down this part used, since new is near 5000. Does anyone know anything about this odd configuration? where I could possibly locate the parts or even if I could retro-fit the system with a different year and if so is that legal for safety?

any hlep would be greatly appreciated

Umm are you SURE they did that exactly? Because I know Chrysler has their normal brake system, then their normal Bendix ABS system, then their crazy rare electrically powered brake system, which uses an electric pump for power brakes, and when the pump goes out, no brakes. I just recently replaced the pump and master cylinder of this oddball type on a Chrysler minivan. But I know nothing of power steering being involved. One time though, I saw an 80s chevy pickup that had hoses from the master cylinder going to the power steering pump. I imagine thats how they make real power brakes, or with an electric pump like Chrysler did. I have recently seen a bunch of the electric powered braking systems in the local junk yard, they seem to be common on Chrysler Town and Country minivans, but not on Dodges or Plymouths. According to my dad, the Dodge Diplomats and RWD Chrysler New Yorkers were fitting with the same thing, but I don't know for sure. Best thing I can suggest is to search the local junk yards for a matching master cylinder and grab it. They're rather easy to remove, perhaps 10-20 minutes. And if you do indeed have the electric pump, get that too.

Anyway, yes you could retro fit the system to use normal non-powered hydraulic brakes. Just go grab a master brake cylinder from a Dynasty, FWD New Yorker or Imperial from a junk yard and install it. I don't know what to do about the lines going to the power steering pump though. Or whether or not a standard master cylinder will have spots for 4 lines or just 2, as an ABS system is likely to have 4 and standard has 2 that each split to 2.

Search ebay, craigslist, and junk yards.

Why not pop open the hood, and look at the master cylinder. You should see some small metal lines coming out of it. But then there should be 2 rubber hoses coming out of it as well, if you really have power brakes, follow those hoses and tell me where they go. If they do actually go to the P/S pump, they would be going to the passenger side and down as well, as that's where the P/S pump is, if you have the electric system, they would be going straight down in front of the master cylinder to the electric pump that sits on top of the transmission.

Let me know!

That link seems to tell you how to replace the electric braking system with a non-power non-abs braking system. Which is perfectly fine if you want to sacrifice your ABS and power brakes.
