Rear Brake Disc Corrosion and Handbrake Caliper Binding
ModerateBrakesWith Nissan's e-Pedal technology delivering aggressive regenerative deceleration in daily driving, the rear friction brakes on the ZE1 see very little hydraulic actuation. In damp UK driving conditions with winter road gritting, the rear discs rapidly suffer from heavy circumferential rusting, surface pitting, and binding slide pins. This is the single most common MOT failure point recorded on ZE1 Leafs at three and four years old.
Excessive squealing or grinding from rear wheels when coming to a complete stop, Visible deep concentric rust bands across rear disc surfaces, Electric handbrake slow to release or causing dragging sensation when pulling away
- Visually check rear brake discs through the alloy spokes for rust pitting and pad contact coverage
- Disable e-Pedal mode and perform several firm stops from 40 mph to assess braking friction
- Review MOT history for advisories relating to rear brake disc deterioration or parking brake efficiency
