Maintenance

Most brake problems are caused by poor maintenance just swapping brake pads every time they are worn without basic caliper servicing will cause long term issues.
  • Always cover brake when cleaning this will help stop brake pad contamination, 
  • Never use brake cleaner after bedding in the brakes only use it before to remove contamination. 
  • Clean the pistons regular with Mineral oil and make sure the piston move freely 
  • Regular brake bleeding is needed at least once a year.
  • 99% of brake problems are caused by the moving parts of a brake poor maintenance or contamination will cause the brake pads to not work properly.
