Even with the SBC unplugged and battery disconnected, there
is still massibe pressure built up in the SBC hydraulic unit accumulator (14bar). This is a very easy way to lose a finger and pop out the caliper pistons.
Please!!! do not do this yourself. The vehicles
computers also need to be recalibrated for new pads so that the
SBC and ESP can function properly.
THIS IS NOT A DO IT YOURSELF JOB!!!!
