1992 Oldsmobile 98

I have a 1992 Oldsmobile 98 that has no Brakes, after the shop said I need a new master cylinder 8 hours later and paying 350.00 for a one installed he gave me the car back the same way I gave it to them,so now he thinks it is the abs and for another 350.00 he can fix it......no way pal and I will get in touch with my cc co so you will not get any money. Any suggestions?

Actually his second guess is probably the right one. If the abs doesn't work then the brakes will not work properly especially if the internal parts are locked up. Check wrecking yards for another one you will get a better price.
