Hello,
1st post please forgive my ignorance...
I get random indicator lights and the brakes feel mushy and act like air in the lines. Dealer changed a bearing hub and sent me on my way.
It started again within 48 hours and am no longer confident in my dealer, so looking for some ideas on where to start.
