this is a typical Fiero problem . the rear brakes are a pain in the butt to bleed
I think you have been here before !!sorry for your pain
there is no problem with any switch no problem with the combination valve ,prop valve.
just went thru this
you need to buy a one way bleeder valve(solo bleeder valve) ,they cost from $8 apair to $12 for one
just follow the haynes or chilton manual direction for bleeding
or read the many,many post in the search feature of this torum at the top right of the page
first ajust the E brake ..loosen the inside cabin lever handle ajustment then ajust the cable that runs along the axle,spray it with penetrant & let it soak
if you do not have penetrant use automatic transmission fluid(a good penetrant) to soak the cable ajuster
If the mechanic has failed you,, common with fiero brakes ,if you have never bled the brakes on a car get a local gearhead YOU KNOW to help ,, the one way bleeder valves make this SO MUCH EASIER
THE e BRAKE MUST BE AJUSTED BEFORE YOU BLEED THE BRAKES , you may have to remove the e brake cable & lever,not difficult just a pain ,if so move the ajuster slowly, so you do not damage the ebrake ajuster seals
a powerful squirt should shoot out from both bleeder valves ,,both rear wheels should turn with the same resistance
Im a bettin that 25% of Fiero,s have improperly bled brakes ,even some that have been serviced at a brake shop.
