IF you talking of a stockish '71 booster, don't waste your time...

do a search for hydroboost, and hook that up....stand your shark on the nose anything stock SUX....literally and figuratively...

I'm beginning to think I have the only C3 with decent brakes. I've run the crap out of it on the track, and the brakes always stop the car hard and fast. The only complaint I have ever had is pad taper wear, a caliper issue. When it comes to strictly M/C and booster issues, I'm completely happy with the performance and pedal feel. I'm currently installing Wilwoods all around (along with a C4 suspension transplant), and I'm hoping this setup feels similar to the original setup.

There is a kit to do this. I beleive it is sold by Zips. It requires some firewall mods and a new brake switch bracket and some time working under the dash (not pleasant). However it has been done and the kit seems very complete.

Here you go:

71-73 POWER BRAKE CONVERSION
Product Number: DB-50071 Price: $359.95

My advice would be to use the stock set up. Purchase the '71 AIM and take a look at the non-power and power installations (J50 option). Power requires a couple of additional holes in the firewall; AIM shows where they go and their sizes. AIM also lists the original parts and part numbers. The aftermarket providers carry the boosters, master cylinders, brake lines, and the vacuum pipe from the base of the carb.

Lemme just say this, ALL GM cars of the shark era had the same pedal feel through the lineup....Caddy down to Chevette, and I have owned many of them, driven most, all across the boards, A B G F bodies all the same as our Vettes....soft squishy what I interpret as being an unsure feeling, any time I ever got one to feel right, just like my '72 vette here, within a week of commuting/driving....it went right back to that soft unsure feeling...it's a very common complaint....even my '85 Dodge van has had that same brake pedal feel since '92 now....when I bought it....wife's 99 Escort has same feel....
Honestly, I think its so much a part of vacuum assist designs, it can't be eliminated for very long, just a tiney bit of wear on the pads/shoes, and it's right back to soft pedal....

the HBoost system don't have that feel, I got a nice stiff easy drive pedal with plenty of reserve travel, and some actual GRIP on those calipers now, IF I want it....NEVER had that feeling b-4 outta this vette or any other car...
the imports I drove from late 70's to late 80's had allmost the same feel, but not as bad sort of 1/2 step between the 2 extremes....

I have to think you are just used to it, consider it normal, and lord knows I lived with it long enough also.....I think the 4w discs on sharks make the problem even more noticeable, and I tried it ALL, but putting on that damn HB cured the car, I tore into the stock booster, but found absolutely nothing rong with it....held vacuum, everything seem home and sealed fine, rubber was in new conditon, no rust except on outside canister....
go figger....

methinks most factories design it that way for women, frankly....I can't think of another reason....

and yes, even just rapid street driving, not HARD, just quick,....I notice pad taper wear also, so they get changed once every 4 years or so....eh...
