Would this also not be a good time to think about upgrading the front brakes if you are willing to spend minimum £200 on refurbishing the originals? Why not spend another £200 or maybe more on getting a bigger front brake setup?.. If you have the money to spend that is.. or.. Save up to do that then refurbish them all at the same time if you do plan to go bigger on the front?.. Rather than paying twice to refurbish again when/if you do move onto bigger and better brakes?..
Just thought that was worth mentioning if you do have any plans to upgrade them in the future
