1st weekend of the year, I went out on new GLocs and rotors and calipers from a few years ago and a fresh bleed. Pedal felt solid on day 1. Felt softer at the end of the day. I figured it just needed more bleeding so did that and it helped but not as perfect as day 1. Lived with it for another weekend.
Last race, I loaded up the car, went home and noticed a huge puddle of brake fluid at the RR tire when I was unloading. The RR caliper was leaking. So I replaced them both rear calipers with Drago's fancy, sexy calipers. While bleeding the brakes, I noticed wetness on one of the front calipers. So I decided to test by pressurizing the brake system and check for any leaks.
Cleaned all the calipers with brake clean and paper towel. Jammed the jack handle between the brake pedal and the seat effectively applying the brakes overnight. Next day, I see telltale signs of leaking from 3 of the bleed screws.
Replaced the front bleed screws with those from a spare, good caliper and repeated the test. Some leaking from 2 of the bleed screws...
Any thoughts on what I might be doing wrong with the bleed screws? Anyone ever have something similar happen?
I usually just tighten the bleed screws with my tiny 8mm closed end wrench to 1 ugga. Am I over tightening? Does position of any orifices in the bleeder screw matter?
Contemplating trying some thread sealant from Speed Bleeders...
