Reuse your current push rod that is between the booster and master.



Thanks! If only I had kept it. Anyone have one to sell?

Edit: Hmnn, I just had a look at page 5 of this topic. There is a photo of a pair of push rods that shows a different version of the S10 booster pin. Also, the poster recommends using it instead of the stock pin.

If you use Rodney Dickman's Big Brake Booster Installation Kit you should have to cut and weld the rod. It's adjustable and works pretty well,

My only criticism of the video is that it took me far longer than 1 hour to install the brake booster. i worked on it for several days - it took me over 1 hour just to get the last nut on the booster to the firewall.

Still this mod is worth it! One of the best things i have ever done to my car.

I don't recall how long it took me to do this years back, but I agree with your conclusion - every time I drive the Fiero I am reminded it is an awesome upgrade IMO....

So, there's a video describing this process of what is entailed in swapping the booster somewhere?

i got my 87 fiero a few months ago.it surprised me how much pedal pressure it took to stop it.MUCH more than my other cars.so i ordered brand name rotors and pads from rockauto.[plus rear calipers since my car had front calipers front and rear].i installed the rear brakes and will install the front brakes though i hate greasing bearings.i may still do the booster upgrade.

A proportioning block with adjustment... https://www.summitracing.co...roportioning%20valve




Hey guys... I wanted to quote this comment from our good old friend Tony Kania who now appears to be banned (don't remember what happened).

The question I have is... how do you know what kind of bias you should have? The last time I did anything remotely SCCA was way back in the late 90s... and it was only a few sessions that I showed up for that allowed me to do a run in the cones. That was obviously over 20+ years ago.

I'm building out a Fiero that will certainly exceed stock brakes and handling, but not by much. I'm looking at probably ~175hp / 220 ft-lbs of torque.

I've upgraded my car with cross-drilled rear rotors just to prevent overheating, but I've also installed the Grand Am brake upgrade kit, along with steel lines and steel braided brake lines.


Don't make fun of me here... but I used a proportioning valve a LOT... in the COMPUTER GAME Need for Speed - Porsche Unleashed. Hahah. So I understand the concept of increasing brake bias to one way or another. I realize the physics weren't real, but I always increased front bias because the Porsches (except the 944 / 928) would always have the rear-end swing out, and it made it easier to drive at the extreme limits when I pushed the car (in the game).


Are there any good tutorials (YouTube) that anyone knows about that explains concisely the dynamics of braking and handling as it applies to oversteer and understeer? I understand what each is, of course... but what I'm asking is... is there a tutorial that explains say... if you install a rear-sway bar... this reduces understeer (but increases oversteer), for example? And as it applies to a brake proportioning valve... (while also understanding brake dynamics ... e.g., if you let up off the gas in a mid-engine or rear-engine car, the back-end is likely to come out.

I'm a bit more comfortable with ever so slight understeer, but with the things I've done to the car (larger rear wheels, poly bushings, larger sway bar, etc...) I really have no idea what I've done to the car. I made most of these changes when I was much younger, and I didn't quite understand any of it back then. I'd prefer slight understeer, but also want to know that my brakes are properly tuned to advantage the changes I've made.


Thanks!!!
