Brakes problem
So the day after I get my car inspected my brakes feel soft. The guy that did the inspection told me that he put some brake fluid in. As I'm pulling up to a red light they damn near go to the floor. I pull over, look around, master is full, I see a line of oilyish fluid on the inner fender well of my front driver. A friend halps me bleed them and I get some air out, still soft though. I get it home, slowly, and I take off that caliper. It's fine but I did notice the banjo bolt for the line was a little wet. About 4 months ago I did a motor swap and had to disconnect my brake lines on the ABS block. When I put it all back together, as I was bleeding I realized that I did not fully tighten the fittings on the ABS block so I was getting some oil/air sputter out the top of the ABS block when bleeding, I tightened it and it seemed to be fixed. Would this cause problems 4 months down the road? I drive this car every day and haven't had problems until yesterday. I also took out the banjo bolt and noticed it was really tight in there.
could over tightening cause the crush seals to be damaged causing a slow leak over the months or could it be a slow occurring problem back when I bled them 4 months ago having air come out of the ABS block? I know those ABS blocks are sensitive and sometimes have to have a tech II bleed. Thought it was obvious when i saw oil on the fender well, looked like it dripped in my wheel from the banjo bolt possibly and sprayed around while driving.
Also when I tried to put the banjo back on it just kept spinning.
