So I just posted in the lap times - setting a 2:15.83 for a new personal best at VIR and having a great time instructing a student in a Corvette made for a spectacular set of days at VIR - great weather, great times. That night things went to shit. On the way home, the pedal felt SOFT. I thought I must have boiled fluid, but checking my master cylinder revealed it EMPTY!!!! (or almost). In my garage a puddle quickly formed around the left rear wheel. My original calipers got "sticky" several weeks back and were both replaced. The new one was now leaking BADLY!! I took it O'Reilly and got a new one under warranty, which was another issue concerning it came with no e brake spring and I had to go back and get the one off my old one, which led to an interesting exchange between me and a manager. I'm thinking this may have been related to the fact that my rear brake pads were VERY low, maybe an 1/8th inch left when I took them off- yikes!! paper thin.... my fronts weren't much better. So I have a couple of sets of rear pads and I got some new front pads ordered from Porterfield just this am as I type. Has anyone else had this issue with replacement rear calipers? Is there a brand I should target? Should I get the O'Reilly shit off the car ASAP before it gets me killed? I'm thinking if these parts store calipers were bad, there would be crash in Lemons and Champ every other lap related to it. I got my daily driver pads in for the week and am just super paranoid now, it took me about 3 hours to get everything squared away last night. Days like the ones I had made me love this and want to kepe pressing on at this. Nights like this, however, make me just want to rest on my laurels and move on to other things. I suppose I could use advise on brakes and words of encouragement to carry on.
