    Chrysler vs Allante ABS parts

    I've found an Allante locally that's for sale, cheap - but the brakes aren't functional. It supposedly sat for 2 years without being touched, after which the pedal now drops to the floor, and the warnings light up the dash like a Christmas tree. I don't have all the specifics at this point, but I do know it's going to need some attention.

    My fear is that it may end up needing a new accumulator, and (depending on how much they played with it) possibly a new pump, before things are restored to working order. Of course, the prices for those parts are astounding.

    I've been doing some reading, and noticed that several FWD Chrysler products also supposedly used the Bosch III ABS system in '88, '89, and the first half of MY 1990. Has anyone here ever investigated the differences between the GM and Chrysler systems? (I'd love to dig into it myself, but don't want to have to buy the Caddy just to do the research!)

    A major auto parts store lists parts with the same names, having similar but slightly different part numbers, and the same stock pictures... no clues there.

    I would expect the parts to be too different to be compatible - but who knows?

    If perhaps I've stumbled upon a cheaper way to obtain the potentially needed pieces for this Caddy, it'd make me much more confident in moving forward. (I don't want to bank on getting lucky, and curing its issues simply through bleeding... though that sure would be nice!)

    Would also be interested in hearing from anyone who has attempted any other brake system modifications/conversions on an Allante in order to eliminate the need for costly original replacement parts. ABS or no ABS, I know there must be other means of achieving power assist at a far lesser price.

    The pump is the same save for the wiring connector, different plug. Simply splice in the Allante connector. I did it. worked fine.

    Carnut,
    Can you give some info of which Chrysler pump you used off what car. I'm trying to get my brakes to work without spending a small fortune on used parts. Chrysler also supposedly used the Bosch III ABS system in '88, '89, as I read in a earlier post that you answered.
    I own a 88 Allante

    The 1989 and early 1990 ( I believe they changed in mid 90 so get the early one.) CHRYSLER IMPERIAL V6-201ci 3.3L F/I has almost the same bosh pump and you can get them rebuilt for about $250. from Rock Auto.
    Just change the connector...

    Re: Chrysler vs Allante ABS parts

    my mechanic was w/ Chrysler/jeep for 10 years, has says the Jeeps from back then Bosch abs is exactly the same.. he replaced the accumulator on my 1987 Allante
    by just unthreading it & threaded the rebuilt one back on - you don't have to replace the whole unit. That was a few years ago & still works perfectly.

    If youre in Tampabay area of Florida - Carls Complete Auto in Largo,,, 727-277-3625 he knows the Allante inside out
    ( as well as all other makes models) & his rates are wayyy lower than any others w/ 12 year/12000 miles parts & labor warranty.

    This is some great information. I would be interested in a sticky thread with compatible replacement parts and procedures for these brake systems, there are becoming some really high prices on ebay even for used brake parts for these cars anymore.

    Re: Chrysler vs Allante ABS parts

    good info guys. I'm diagnosing my 91 brakes after the car sat for 5 yrs outside. I've always rebuilt master cylinders on previous cars but it seems like there isn't a kit available for these? I've read dozens of threads on it but I'm struggling with dropping $900 to fix it? Someone outhere is remanufacturing these? Where are they getting the seals? Does anyone have any info? Can i just separate out the master cylinder from the whole assembly and repair or replace that? I've checked out the pump it appears ok. Any help appreciated. BL
