Brake corrosion and seized calipers
The most common EV brake problem comes from too little use.
You'll learn
- Understand brake corrosion and seized calipers
- Know which checks an owner can do and which need a professional
- Recognise warning signs early
Overview
Because the brake pads rarely work hard, rust builds up on discs and caliper slide pins can stick, especially where roads are salted.
In depth
Signs: grinding noise, pulling to one side, uneven pad wear, a rusty ring on the disc or failed brake tests at inspection.
Use the brakes now and then
An occasional firm stop from moderate speed in a safe place cleans the discs.
Key takeaways
Remember this
- EV brakes rust from lack of use.
- Occasional firm braking helps.
- Have calipers serviced yearly in salty areas.
