A worn anti-roll bar bush can cause severe, intermittent brake pressure loss that is easily misdiagnosed as an expensive ABS pump failure. Kirby of Kerbside Mobile Mechanic demonstrates how lateral movement in a damaged anti-roll bar forces contact with the brake caliper, pushing the piston back and creating a dangerous “no brakes” sensation during cornering.
Kirby explains that the main dealer failed to identify this mechanical interference, previously attempting an unsuccessful master cylinder replacement before suggesting an unnecessary £1,200 ABS unit. By sourcing aftermarket split bushes instead of the full £500 anti-roll bar assembly required by the manufacturer, Kirby provided a cost-effective, permanent solution for the customer.
Beyond this diagnostic breakthrough, the vlog showcases the technical diversity of the modern independent workshop. Kirby guides viewers through a precise DSG gearbox service, emphasising the importance of maintaining the fluid level within the strict 35°C to 45°C operating temperature range.
The update also highlights the intensive labour involved in major engine repairs, including a Ford Transit Custom wet belt failure that necessitated a cylinder head rebuild. Finally, the feature offers a glimpse into a semi-restoration project on a classic Ford Cortina, illustrating the varied workload managed by an independent technician.
