McLaren and the National Highway Traffic Safety Administration (NHTSA) have issued a recall of 19 vehicles as a result of a faulty part in their brake systems.
The recall covers one McLaren 570S, one 600LT, seven GTs, and 10 720Ss manufactured between July 8, 2019, and March 15, 2020. These vehicles may contain a banjo bolt that was improperly manufactured by the supplier, according to recall documents.
The banjo bolts were used for brake pipe assemblies between the flexi-hose and the caliper. These bolts are designed to have holes drilled in them to allow hydraulic fluid to pass from the lines to the caliper. Some may not have had the holes drilled into them, though, meaning that there is no braking power to that corner of the vehicle.

Vehicles affected by this issue will tend to pull in the direction opposite the side of the car with the defect since the side of the car with the bad banjo bolt has less braking power. This could be dangerous, particularly at high speed, and may increase the risk of an accident.
Owners who have the defective brake could be forgiven for not noticing it, though, since McLaren says that its electronic stability control system may work to adjust wheel speed and mitigate the pulling effect of the faulty brake, especially at low speed.
The remedy for the problem is pretty simple: a McLaren technician will just inspect the brakes to find the defective banjo bolt and will replace it with one that works. The automaker, though, has not yet provided a timeline for when it will instigate this recall.
