Is there a cavalier/grand am/etc caliper that is a direct fit to the fiero front for an 85? I have 04 cavalier calipers that are to big for the stock bracket

Hopefully something bolts up without an adapter.

I have drilled/vented rotors off a cavalier i would like to use.

Also whats a good auto-x, road race pad to go with em?

I have read on this forum that the "Performance" brake package sold by the Fiero Store for the Fiero was in reality, modified grand am front brakes. The package is pretty pricey though.

yes, I think mine are '94 Grand Am, and - they also go on the opposite side - as in the grand am passenger side caliper goes on the Fiero drivers side.

also - I think there is some grinding that needs to be done on the caliper bracket

The tang on the spindle that faces the back of the rotor has to be ground for clearance of the thicker GA rotor. I used 91 rotors, calipers and pads on my 4 wheel conversion. If you do the back brakes, too, it just bolts right up. Remember that the bleeder screw has to be on top of the caliper and you'll do fine.

Can you explain a bit more in detail what grinding needs to be done? I probably could figure it out when I look at it but would like to know ahead of time.

no, I cant - I bought the Fier STore set, and it comes with brackets - but - the posts above does describe it, and I do think there are more posts & webpages with more detail.

yes, they replace the existing Fiero brackets.
the kit also comes with new bearings & grease seals for the hub.
you will have to get the existing Fiero rotor cut down to just a hub, and also replace the lugs with longer ones, so you can put on the vented rotor

If you take your existing front Fiero rotor to a machine shop they can turn off the rotor, just leaving a hub.

Im not worried about the hub, I have a laythe/mill here to do that, I just wanted to know if the caliper was a bolt on, as I have 04 calipers that are slightly to long to fit both mounting holes, so I was hoping the older calipers would be a direct bolt in on the front.

GM started using Anti-Lock brakes on 91 Grand Ams and 92 Berettas. Those calipers and rotors are different. You need to use 85-91Beratta, Cavalier calipers, or 85-90 Grand Am Calipers. Those are the ones that match the mounts on the Fiero. The brackets still have to be shaved on the front, and you may have to bend the dust plate back a little. I've done this on my rear wheels and plan to do the front after I get my other Fiero running.

Autozone part#

Calipers C154 and C155
Pads MKD289V
Rotor 5558B
Bolts H5047

these are 86-91 Beratta and 85-90 Grand Am parts

Thanks for the info Nick,

Does just the bracket thickness need to be grind down?

Thanks
