Now that the garage is ready I start taking the brakes apart.
There’s definitely some residue in one of the cylinders. A sign that the brake master cylinder is gone.
It’s not the only problem though, the car has become “a smoker” .
During october I keep working on the brakes in the weekends. Progress is slow since I’m not a trained mechanic and a lot of questions pop up with each bolt that comes loose, so time is divided between the garage and internet research. One of those things is the presence of oil in the air filter.
