THE BIGEST PROBLEM WITH FIERO BRAKES IS PEOPLE BUY CHEAP PADS,make sure you have top quality pads on the front
if any doubt replace with top quality , like wagner thermo quiets ,or Fiero store Carbomets
never rebuilt the Fiero master cylinder buy a new one , the bores do not wear evenly they cone, sorry!
read the OGRE brake site,read again take notes
jack up the rear of the car when bleeding, you can avoid bench bleed & do it on the car
fill M/C partially for the first bleed to make sure all dirty fluid is expunged
never screw the rear caliper actuator ajustment screw more than a little bit
if you have screwed the actuator screw in & out good chance the thin seal gasket is harmed
jack up all 4 wheels & make sure the wheels spin equaly,check carefully,a tight wheel is often a bad hose,,rubber hose are great,
use only FIERO STORE calipers if possible
if you have the Haynes manual, you can rebuilt your rear calipers since you are in Britain ,,use extreme care ,rebuild one at a time so you have the other caliper in case of error,, many company rebuilt calipers fail
lay all the caliper parts out on a table .preferably on a light color cloth
if your rear calipers do not leak & the pistons move, leave them alone,,flush them good,real good
back off the Ebrake in cabin & back off main Ajusters along the back frame ,spray with penetrant ,make sure every think is free
check ebrake cables if frozen at bends you can slit sheath to soak cable with penetrant then wrap with electrical tape
make sure the Ebrake cable is properly mounted to the caliper lever
do not ajust E brake untill the brake works proper Ebrake ajustment is critical make sure that each wheel is equal length
the fiero rear caliper & Fiero brake system is a pain in the buttocks to bleed
you have to pump a lot of Fluid thru the fiero system
make sure the Master cylinder fluid looks pristine, there should be no dirty fluid bleeding back in
you must have a firm solid squirt of fluid out the rear bleed valves on each rear wheel,,once you have pedal do not depress pedal all the way to the floor
your booster is not the problem,, very seldom would a booster work , then later not work then work again,but cheak it out
you can spray penetrant into a bottle & add 25% automatic transmision fluid for a better penetrant
if you do not need the Ebrake for inspection ,,buy the grand am/berreta Calipers rotors & pads this is a direct swap for the Fiero rear brakes ,you loose the Ebrake .but this one modification works a miracle in braking & is not expensive
use cheap brake pads with the berreta/grand am rear brake swap to keep braking equilibrium ,so the rear end does not overpower the front brakes
having the berreta brakes on the rear work excellent, I was surprised how great this simple swap worked
Plan on replacing your clutch slave piston ,with a dual seal piston from rodney dickman Fiero parts
