Please describe what you mean by surge.
If you mean that it pulls HARD to the left, you probably have a bad caliper on the right side. They should be fairly cheap if you buy a rebuilt unit and if you are confident enough to do the work yourself.
Be sure that you bleed the system properly after replacing that caliper. If it does not solve the problem, please leave another reply and we can do further diagnostics.
