The importance of checking/changing your brakes.
A personal note from your mechanic;
In my experience owning CMM Automotive, I have found that many customers allow their brakes to run down to below 30%. At this point, you risk seriously damage your vehicle and endangering the life of others. At 30%, the owner has to make the decision to replace their breaks when it is cheap, or continue below 30%. If they choose to do this, they run the risk of not only having to replace their brakes but all the components which control the brakes. This can end up costing hundreds of dollars and possibly someones life.
