What Causes the Brake of an Electric Tricycle Not to Rebound
2 Answers
Damaged tension spring. Below are the relevant explanations: Damaged spring: There is a return spring in the brake system that allows the brake to return to its original position after operation. However, if this spring is damaged, it will affect the operation of the brake system. Solving this problem is quite simple; the owner can replace it with a new return spring. Front axle: When there is a malfunction with the front axle of the vehicle, it can also prevent the brake from rebounding. The owner can first check what issues the front axle might have, and if unable to resolve, should send it for repair as soon as possible. Brake cable: Sometimes, the brake cable can also develop faults, causing the brake not to rebound quickly to its original position. In such cases, the owner should not panic; repeatedly applying the brake a few times might help restore normal function.
Over the years I've been in vehicle maintenance, electric tricycle brakes failing to retract after being pressed is a common issue. The most likely cause is a broken or loose brake return spring – if the spring loses tension, it naturally won't snap back. Another frequent culprit is rusted and seized brake cables, especially after riding muddy roads in rainy weather without timely cleaning. Mud solidifies inside the cable housing, causing the steel wire to lock up completely. I've also encountered cases where the brake arm pivot rusted solid – upon disassembly, it was completely corroded into an iron lump, beyond saving even with generous grease application. If you're checking this yourself, remember to disconnect power first. Use a wrench to loosen the brake cable and test manual retraction. If there's significant resistance, it's almost certainly due to aged cable housing. This directly concerns personal safety – if you find a broken spring or cracked cable housing, replacement is mandatory.
