Toyota Corolla 2015, 58,000 miles. Well maintained.
Symptoms are, after sitting overnight the brake pedal is a little low and hard, as if the brakes were pumped after the engine was turned off. Once the engine is on the pedal comes up and brakes are normal. Even sitting several hours during the day the ‘feeling’ is normal.
Does this sound like a leaking master cylinder? Any other ideas.
Not a job I want to tackle myself but want to be prepared when I talk to my local shop. Of course will start with symptoms and not just ask for a mc replacement. But my shop is smart enough to get the back story before working on a job.
