小型混凝土攪拌車複位慢的表現是小型混凝土攪拌車在製動減速後，鬆開製動踏板，車速不能很快地提高，嚴重的甚至難以起步，小型混凝土攪拌車發生製動發咬的故障後，可以按如下步驟檢查並排除：
The small concrete mixer has a slow reset, which means that the speed of the small concrete mixer can not be increased quickly when it releases the brake pedal after braking and decelerating, and it is even difficult to start. After the small concrete mixer has a brake seizure fault, it can be checked and eliminated according to the following steps:
1、如果踏板自由行程適當，主製動閥排氣口有氣體排出，掛檔起步，如果能起步，行駛一段距離應檢查製動鼓是否發熱，如發熱一般是由於製動蹄和製動鼓間隙太小所致。應檢查製動蹄和製動鼓的間隙，使之保持正常。
1. If the free stroke of the pedal is appropriate, there is gas discharged from the exhaust port of the main brake valve, and the vehicle starts in gear. If the vehicle can start, check whether the brake drum heats up after driving for a certain distance. If the brake drum heats up, it is generally caused by the small gap between the brake shoe and the brake drum. The clearance between the brake shoe and the brake drum shall be checked to keep it normal.
2、如果不能起步，可踩下踏板，將變速杆置於空檔，然後在鬆開製動踏板的同時，檢查各製動氣室的推杆能否回位。如果是某個製動氣室的推杆不能回位，即是繼動閥卡死，或是製動蹄回位彈簧太軟，斷裂造成的，或者是前製動蹄銷鏽死造成的。
2. If it is not possible to start, step on the pedal, place the gear lever in neutral, and then check whether the push rods of each brake chamber can return to their original positions while releasing the brake pedal. If the push rod of a brake chamber fails to return, it is caused by the stuck relay valve, or the brake shoe return spring is too soft and broken, or the front brake shoe pin is rusted.
3、檢查製動踏板的自由行程，或者是在貯氣筒氣壓達到規定之後，踩下製動踏板，然後在鬆開踏板的同時檢查主製動閥的排氣口有無氣體排出，如無氣體排出，踏板無自由行程，說明是主製動閥的排氣閥打不開，應調整主製動閥拉杆，使主製動閥的活塞杆和排氣閥之間有正常的間隙，使製動踏板保持正常的自由行程。
3. Check the free stroke of the brake pedal, or step down the brake pedal after the air pressure of the air reservoir reaches the specified value, and then check whether there is gas discharge from the exhaust port of the main brake valve when releasing the pedal. If there is no gas discharge, the pedal has no free stroke, which means that the exhaust valve of the main brake valve cannot be opened. Adjust the pull rod of the main brake valve to make sure that there is a normal clearance between the piston rod of the main brake valve and the exhaust valve, Keep the brake pedal at normal free stroke.
