Yesterday morning I went out early to a nice straight, level, rural road to actually try a panic stop. I'm easy on brakes, not waiting to the last 75' to start braking as I see lots of people do. In 310,000 miles, my Elco has had only two brake jobs, and both initiated by leaky wheel cylinders. So thinking I needed to to actually see what happens, I tried a true panic stop. The rears locked up, and the pedal pressure wasn't too severe. Coulda pushed a lot harder. I looked at the Monza ventilated rotors yesterday, and I can't see how they could possibly be drilled in a 5 bolt pattern without the four ribs interfering with the studs. Checked my wheels yesterday as well. The are dual pattern and using 5 on 4.75.
For they time being, I'm going with the pad change. I only put maybe 1000 miles on it a year and I'm pretty easy on brakes. Also, at 73 years of age, I prolly won't see 20,000 miles before they take it away from me. However, if the pads don't work out, then it sounds like the S-10 stuff is the answer.
I'll report on the brake pads when I put them in. May be a bit. Fuel pump failed yesterday. On my "want" list is changing to a Camaro fuel tank, in tank pump, to get ready for the FI on my list. It may be time, as the present pump cost the better part of a change over.
