This GTA is not mine nor my son's, and it's a rust free unit which is unlike most all of the rust belt beauties that we usually build/work on. So I ***/u/me that there wouldn't be a corrosion issue.

I pulled off the rear calipers and found the sliding sleeves that ride on the o-ring were rusted and not sliding. The passenger side was not moving at all and the driver side was better, but not moving properly. The result is that the pads were too far from the rotor after the brakes were released causing an excess amount of fluid needed to have them engage the rotor. This caused the brake light from the combination valve switch and no rear brakes on the 1st pump. A couple of minutes with a scotch roloc disc and a little caliper grease was needed.

Tony's post about panic pushing of the pedal and Olnolan's video put me onto it. And lmsport's last post describing the excessive bias was what got me thinking. When I was 'panic stop' pushing the pedal with no light and good rear brakes the light bulb went off in my head. Only took me a week or so - hehe.

Thanks for the help everyone - it was entertaining, educational and interesting - at least to me lol.

Tomorrow it's supposed to rain in monsoon fashion - 3" or so - and be in the 50-60 degree range. Which should do it for a temporary cleaning of the salt off the roads. Perhaps I can get in a couple more burnouts and brake tests.

Thanks - Jim
