Noticed while doing a burnout this weekend my back brakes do not seem to be fully releasing after setting the line lock. I would be doing a burnout at ~50-55mph and upon releasing the line lock the speedo would bury the needle. Would the proportioning valve play into this? Anybody ever see something like this before? Line lock is installed between the master cylinder & prop. valve.
Car has a new master cylinder, new brass proportioning valve, new front calipers, new rear wheel cylinders.
