bad brakes

[Stephen Beltz]

I bought a 1990 supercoupe for 500 when three ladies pulled off the freeway after they overheated it. I replaced the radiator which fixed that problem.
It has a bad harmonic balancer and no power brakes. Im having problems fixing the brakes Iv replaced the abs computer both relays on the passenger side firewall and next on the list is the master cylinder and electic pump. would it be worth it to switch to a vacuum or hydrolic system?

it could be simpler to swap over to non abs vacuum brakes, but thats a matter of how much you like the car. those older teves abs systems are SO prone to failure. check the pump to see if its getting power its a 4 prong round plug over there by the master cylinder. it could be the pressure switch or the pump itself. there is a good write up on vacuum brakes the the tech forums. just use the search function:)
