Anyone else have a brake cylinder leak? I've got about 60,000 miles on my car and had the brakes done about at about 47,000 miles. About 3 months ago I had a "Brake Fluid Level Low Service Now" light come on. I brought it in and they did a quick inspection and said they found no leaks and topped off the brake fluid. Last week the light came on again and I took it in and now they're saying it's a brake cylinder leak and it'll cost almost $800 to fix. Has anyone else had a brake cylinder leak?
