Before a road accident,my car had been recently serviced and the brakes were very good. After the accident, the brakes were spongy and air had got into the system. In the accident,the car had impact damage on the near side wheel and the off side wheel had bumped up a high kerb.I had also braked excessively to try and avoid the collision. There was no evidence of any damage to the braking system.How could air have got into the system?
Sounds like you damaged something that is causing brake fluid to leak somewhere. Could be a line, a fitting, a wheel cylinder? If fluid leaks out it has to be replace with air. It's not so much how did air get in but where is the fluid leaking? Other wise the repair guys fixed some leak in the brakes and never bled all of the air out properly. I think I'd check in with the repair facility.
