Installation

Start buy undoing the brake hose be sure to pinch it off with Vise Grips
to keep from letting all the fuid from running out into your work area

remove the rotor and then remove the old caliper bracket using a 19mm socket and rachet and remove the backing plate

the area I'm pointing to must be smoothed and leveled using a grinder or heavy file. This is to make a surface for the adapter
to bolt to and drill out the old holes to 12mm (17/32) as the old threads are no longer used

This is a comparison of the two setups the stock on the bottom and the Vette on top
the rotors are 88 and the calipers and brakets are 84 to 87

This is how the finished spindle should look after drilling and leveling out and a little cleaning

install the cut hub and new rotor then bolt the adaptor to the brake bracket as seen above using 12mmX1.75 cap screws

with the adapter and bracket together slip the pieces over the rotor in the fashion
displayed in the above 3 pic and the rotate it into the bolting position

Bubba, that is awesome! A + for you, more if I could.

Two questions: The 'vette rotors: do they come with the same bolt pattern as the Fiero, or do those need to be drilled? I see that they seem to have an extra set of 5 holes in the rotor.

Other than cutting off the Fiero rotor itself, does it need to be machined like other brake conversions?

Thanks for taking the time to share this brake upgrade!

Now bleed the front brakes install the wheel and your done

What about the lower shock mount... i remember reading that the PBR caliper will have clearence problems with the shock under full turn of the wheel

once you cut off the old rotor knock out the studs put on the consentric ring onto the rotor then place it into the vette rotor and drill the new bolt patern between
the original holes easy to do

I have a question about the master cylinder years. I found a couple on ebay 72-80 is the older style cast units. Is this the one you are talking about?

Bubbajoexxx, was there a reason you went with the stock Fiero bolt pattern, since you went this far why not stick with the Vett bolt pattern for a wider veriety of rim choices?
