How to deal with no oil output from the rear wheel of the Bora ABS pump?

Generally, it cannot be repaired. It is recommended to first use compressed air to blow the holes of the ABS pump. If the problem cannot be solved, the ABS pump needs to be replaced. The following are the methods to deal with no oil output from the rear wheel of the ABS pump: 1. Check whether it is caused by carbon deposits; if the vehicle has run about 20,000 KM, focus on checking and cleaning the throttle valve; check, test, and replace the spark plugs; confirm the quality of the gasoline added; test the ignition switch; test and inspect the starter, fuel pump, sensors, and other components related to the starting and fuel supply system; 2. After powering on, do not start immediately. Wait for 30 seconds to 1 minute before ignition to see if there is any effect; in any of the above cases, if the car does not start at the first attempt, be sure to wait for 15-30 seconds before trying again to protect the battery from over-discharging and extend its service life.
Encountering a situation where the Bora's ABS pump isn't delivering oil to the rear wheels is quite common. I've helped others deal with similar issues before. Possible causes include clogged oil lines, ABS module failure, or damaged sensors. My advice is to first check the brake fluid level to see if it's low or deteriorated. If the fluid is fine, proceed to diagnose the trouble codes—an OBD scanner can pinpoint the exact issue. If you don't have the tools, a simple method is to drive the car onto a flat surface, press the brake pedal, and listen for any unusual noises from the pump. If the oil line is clogged, try cleaning the lines or replacing the filter. If it's a sensor issue, you'll need to replace it. Repairing the ABS pump can be costly, so some mechanics recommend cleaning it instead of replacing the module outright to save money. From a safety perspective, never take this lightly, as it affects braking performance. If the tires lock up during emergency braking, the car could lose control. For regular maintenance, periodic checks of the brake fluid and wiring are crucial—prevention is always better than dealing with repairs later. Remember, if you can't handle it yourself, take it to a professional repair shop right away—don't push your luck.
Having driven my Bora for many years, I once encountered an issue where the ABS rear wheel wasn't delivering brake fluid. There's actually a method to handle this: First, check the fluid level and color - if it's black or leaking, you'll need to top it up or fix the leak. Next, inspect the fuses and relays; if they're blown, just replace them, which only costs a few dozen yuan. If that doesn't solve it, the problem might be a faulty solenoid valve in the ABS pump, requiring disassembly for cleaning or replacement. In my case, the brake line was completely blocked, but the mechanic restored it by flushing with cleaning fluid. Be careful during the process not to damage the wiring, and I recommend recording disassembly steps with a video first. Safety-wise, if the rear wheels aren't getting fluid, braking becomes uneven, making the car prone to skidding during turns, so avoid high speeds when you notice the issue - drive slowly to a repair shop or call for a tow truck. To save money, get quotes from several shops; cleaning costs about half as much as replacing the pump. Regular maintenance is crucial too - I check my braking system monthly to prevent recurring issues.
