How to Solve the Rear Wheel Lock-Up Issue in Santana?

[MargaretFitz]

The solutions for rear wheel lock-up in Santana are as follows: 1. Handle according to the fault code: When the wheel locks up, it usually displays a corresponding fault code. Each fault code corresponds to a different type of issue. Simply address the problem according to the fault code. 2. Inspect related components: Check the parking brake switch, brake switch, and ABS indicator light. 3. Control unit: There may be an open circuit between the PL terminal of the control unit and the ABS indicator light. Also, check if there is voltage between the +B terminal of the control unit and the vehicle body. 4. Install an anti-lock braking system: Installing an anti-lock braking system (ABS) can effectively solve the wheel lock-up issue. For vehicles without ABS, if the brake pedal is pressed while driving, the wheel speed will rapidly decrease.

I've encountered rear wheel lock-up several times, mainly due to the Santana's drum brake system being prone to rust or jamming. There could be several reasons: first, the brake wheel cylinder (that cylindrical component) rusts and seizes, affecting brake shoe separation; second, the brake drum expands and deforms, with severe rust after excessive moisture ingress; third, the brake shoe friction material wears out or ages and sticks; fourth, the adjustment mechanism malfunctions, with the handbrake cable being too tight. The solution is, first, don't rush to start, try gently pressing the accelerator to reverse and move a few times to see if it can shake loose. If that doesn't work, you'll need to remove the tire and manually tap the brake drum or lubricate the sticking points. I recommend avoiding parking in the rain and regularly cleaning brake components. If it really won't come loose, quickly go to a repair shop to replace the wheel cylinder or shoes, don't delay driving safety.

Every Santana owner knows rear wheel lock-up can be quite annoying. Here's a practical solution: First, park and turn off the engine, then ask a friend to help push the car backward—sometimes this can loosen it. If that doesn’t work, remove the wheel to check if the brake pads are stuck. Spray some WD-40 to lubricate rusty spots and manually reset the components. Common causes include severe rust, bearing issues, or detached brake shoes—DIY fixes with basic tools. For maintenance, service the brake system every six months and clean it to prevent moisture buildup. If you can’t fix it yourself, don’t force it—just visit a repair shop for a quick, hassle-free solution.

Rear wheel lock-up is extremely dangerous; I've seen cases where it nearly caused accidents. Stop the vehicle immediately and avoid driving further to prevent loss of control. Brake lock-up may be caused by aging components, water corrosion, or improper adjustment. Safety first—call professional rescue services for repairs, as they can inspect and replace damaged parts. Remember, prevention is key: regularly check the handbrake system and brake drums, and avoid parking in slippery areas.

I'm a hands-on person, and dealing with a Santana's rear wheel lock-up is simple and cost-effective. The issue is often caused by rust or brake shoe sticking. Purchase a basic tool set (costing just a few dozen yuan), remove the wheel, clean the rusted spots, and lubricate the moving parts with grease. If the wear is severe, buying new brake shoes online for replacement is also inexpensive. If on a tight budget, opt for local small repair shops instead of 4S dealerships. Regular maintenance with some rust inhibitor can extend the lifespan—easy to do and saves money.

Last year during the rainy season, I was driving a Santana for a business trip when suddenly the rear wheels locked up, giving me a cold sweat. Trying to reverse didn't help, and later I had to tap the brake drums on the roadside to loosen them. It turned out that excessive water accumulation caused the wheel cylinders to rust and stick. I promptly went to the repair shop for a thorough cleaning and lubrication. Sharing this to remind everyone to check the brakes after parking in humid weather to prevent similar issues.
