Brake problems are best dealt with before they become major problems as brake issues can cause unsafe driving conditions and lead to more costly repairs. On our 5,000 Mile Service and any major service, we will inspect the brake system for leaks and measure the brake pads thickness.  This will minimize the chance of a brake problem between maintenance.  Unusual noises or a vibration while braking can also indicate problems related to the brake system,  these should be dealt with immediately.
