MarkMontereyBay (4/25/2013)[hr... He is having problems with the dual master cylinder being too close to the stock log exhaust manifold. He said it is boiling the brake fluid....
I bought an inexpensive replica Corvette Disk/Drum MC on the 'bay (with a cool finned cover), along with a combo valve. I ended up cutting a spare brake push rod to fit.
Installation pics here. The MC was a close fit with less than an inch clearance from the stock exhaust manifold. An extended heat shield would not fit, due to the width of the Corvette-style MC. I ended up cutting a scrap piece of self-adhesive fiberglass-backed aluminum heat shield material, and applied it to the bottom of the MC. This seems to work well. This week I also had the exhaust manifolds thermally coated, which should reduce the under hood temps.
I'm pretty happy with the Grenada/Corvette setup for the brakes. Even with the front power assist, the brakes require a firm foot. They are, however, consistent and reliable, and I haven't had any fade issues.
I really like the slightly lowered stance from the new spindles and Aerostar springs. I
shimmed the lower bump stops and have not experienced any tire-rub. The spindle radius arms are at a different angle than stock, and interfere with the turn stops on the lower a-arm at full lock... this keeps me from getting the tightest possible turning circle. I could trim the turn stops with a grinder, but I haven't noticed any issue with the turning radius so I probably won't bother. I also don't like the idea of cutting on an otherwise stock a-arm. All of the other mods I've done to this car are reversible.
