Hi, my brakes keep sucking in air after a few days of being bleed and travel to the floor. The garage has changed the master cylinder the servo and ABS module and it is still the same. I have had this issue for around nine months and two separate garages cannot seem to find the cause. There is no loss of fluid just air coming in, the garage have advised that all the air is in the front brakes. Any advise?

Hey C4RL,

There is only one way air can be getting into the system and that is through the seals of the brake calipers or wheel cylinders. I have seen this problem before because the seal are meant to hold fluid in and when you let up on the pedal they can allow air in.

Please let us know what happens.

Best, Ken
