INSPECTION AND MAINTENANCE
With the engine running, measure the dis­tance between the brake pedal and floor carpet when the pedal is depressed with approximately 30 kg (66 lbs) of force. The minimum distance required is as specified. Since your vehicle's brake system is self­adjusting, there is no need for pedal adjustment. If the pedal to floor carpet distance as measured above is less than the minimum distance required, have your vehicle inspected by a SUZUKI dealer.
NOTE: • When measuring the distance between the brake pedal and floor wall, be sure not to include the floor mat or rubber on the floor carpet in your measurement. Measure the distance at the brake pedal's side facing toward the passen­ger's door.

Check the parking brake for proper adjust­ment by counting the number of clicks made by the ratchet teeth as you slowly pull up on the parking brake lever to the point of full engagement. The parking brake lever should stop between the speci­fied ratchet teeth and the rear wheels should be securely locked.
