Just purchased a 2007 Honda Ridgeline. It's in great shape. However I'm having an issue with the brakes. Has a squishy brake pedal. Took it in and had the brakes bled. Was good for about a week. Had them bled again. Same result. Have now replace the master brake cylinder. Was good for about two weeks. Having same issue.Have been told it could be the ABS control module actuator.
Any suggestions would be greatly appreciated.
Thanks

Hello, as others have mentioned "squishy", spongy" etc. is open to interpretation. What specifically is occurring that feels different from before, after and then a week after you drove it as far as the brakes feel? Does the brake pedal sink as you brake or once you have stopped? Do the brakes grab harder then after a couple of weeks does it take more effort? Are you going to the dealer or a private mechanic?
There is a definitely a different brake bleeding sequence and it must be followed because of the ABS system. Make sure they started at the front left (driver's) wheel then going clockwise. The next would be the front right (passenger) wheel, right rear wheel and last would be the left rear wheel. Also have the system checked with a scanner. See if any codes are being thrown. Do not change the ABS unit without first knowing if it is putting out any codes.
If you have a private shop doing the work you may want to take it to the Honda dealer before letting a private shop tell you it is a ABS unit unless they do a lot of Honda's. Test them, ask them which wheel they bled first. Old school shade tree mechanics as myself would assume it would be the wheel furthest from the master cylinder. One thing I have learned working on newer cars is you need to have a shop manual with cars you are not familiar as the old rules just don't apply. Good luck and safe driving!
