Handbrake cable adjustment nuts are above the heat shield below the Kangoo handbrake lever. You must ensure the automatic take up mechanism on the drum brakes is OK before adjusting the cable. For rear disc brakes, confirm the levers on rear calipers are not seized. I fitted grease nipples on mine. Injected red rubber grease to avoid damage to seals. Use large flat washers when you refit the heat shield. Sticking a vibration dampening sheet to the back side of heat shield also strongly recommended. Buy Peter Russek's Pocket Vehicle Manual for the Kangoo. Covers 1.5 & 1.9 diesel from 2001 to 2006 including Trekka and Nissan Kubistar.
