So, the young mechanic first tells me he does not see anything, I then tell him did you check the brakes in the front, he walk back to the truck and call over another young mechanic, spins the wheels on the lift for about 5 minutes then talks to the service manager, who then tells me there is a very small leak in the front right wheel and he is going to order the part. I think its total BS because I have no oil on the floor of my garage and no low pedal, plus if its a bad drivers front brake line, the truck would pull to the left when braking hard. I can see this is going to be a huge headache for me. Any master mechanics out there that might have a little advice or experience with my issue.
