If there are no symptoms, then why not just top up the master cylinder reservoir periodically?

alozzy said:Agreed, with a lack of symptoms it seems like the dealership is trying to scam him. An independent garage might not want to work on a repair, but they should at least be able to verify that the master cylinder needs to be replaced.
Iirc, the master cylinder , control module and the electronic brake booster are all one assembly -- the "Intelligent Brake Unit". :roll:powersurge said:I don't know why there is so much cost and labor for a master cylinder repair.. It is just a reservoir/pump that is attached to the car with 2-3 bolts...

Take it to a brake shop, an auto repair that specializes in brakes. They should put it on a lift and inspect the calipers at each wheel along with the master cylinder to find the source of the leak. The fluid has to be going somewhere and it should be visible.

You could get a paper towel and pat it along the bottom of the master cylinder to see if it gets wet spots. That would indicate the issue was with the reservoir or seals of the master. If it is dry, then the leak is probably at a piston seal on one of the calipers.
The thing is, who uses brakes on an EV anyway? I just lift the throttle and let the regen slow the car down. If you are looking far ahead you can time the stoplights too and never hit the brake pedal.
