Hi All, my brakes have gone low 2 weeks after brake fluid service. Pedal is basically right to the floor. Any diagnosis.?
Sounds like could be the master cylinder. Check the fluid and look at each caliper for fluid leaks. It’s possible whoever did that flush left a bleeder loose. That would cause the problem. Good luck

Either the bleed screw was left slightly open or there's still air in the system. I suspect air tho. get someone with a powerbleeder to rebleed the system
Air in the braking system
Thanks for the replies. It was Bosch that did the brake flush. Gonna take it back to them
