Inspections of brakes are a must and they have to be done regularly and whenever wheels are removed or when the brake system is in question. Some indications that may be noticed on a vehicle with potential brake system flaws include pulling to one side, squealing or dragging sounds during braking, pedal remaining quite low or its vibration, as well as leakage of the brake fluid which may sometimes be seen around the inside part of the tire or wheel. When inspecting disc brakes, check for two pads (one outer and one inner) in each caliper and observe their thickness through an inspection window; if below minimum thickness replace them. For a more accurate measurement or if in doubt, remove and clean the pads, re-measure them and check disc thickness with micrometer. Also evaluate brake lines and hoses for any damage, wear, deformity or leakage particularly at rubber hoses near calipers and fix related problems by repairing rerouting or replacing them. Besides, carry out several tests on brake booster, the parking brake's effectiveness on a steep hillside should be considered while examining brake pedal height/freepay can help in adjusting it so as to ensure proper operation of braking.
