This is what happens when you lag on a rear brake job. Left rear cylinder failed, r/h rear wheel locked up at over 110mph on the 78 mountian pass one year ago; 100 mph tagged a guard rail going sideways. I now have Toyota calipers with vented rotors up front, and 240sx calipers and disks in rear. All SS lines, and high volume master cylinder with dot4. I am broke. don't be dumb like me.
