Aquired this incomplete project car with this front end set-up. What brakes and struts are these? "A" claipers and boge struts?
My problem is that I sometimes get a loud brakes sticking noise. It seems to occur after the car has been driven awhile and when I go around a sweeper type turn. The noise level depends on the speed. Very loud at 60mph, a slight squeek at 10mph. When I touch the brakes it goes away. If I stomp on the brakes it seems to right it self and stop the noise until it decides to do it again. Another words it doesn't happen on every sweeping left or right turn. I can fly up a canyon road and it won't do it at all. But then make a very gentle sweeping turn and it kicks in. This last Sunday, I took the pads out, cleaned everything up, applied anti-squel brake grease, checked and slightly tightened the front bearing nut. The brakes work great, solid pedal good feel no squeaking. But after a test drive it did it again. Is it a bad bearing? Brake piston sticking? Anyone have a similar experience. I took this picture last night after a drive and it kicked in just as I was turing in to my street and garage. Note the marks on the rotor. Didn't notice that Sunday and you can not feel it. Just visual. Attached thumbnail(s) Attached image(s) |

You need a new rotor. It looks fuched up! bolt the wheel back on, with the car jacked up. Grab the top and bottom of the wheel and pull/push to see it the wheel feels loose. This would indicate a bad bearing. Pull the dust cap and see if the spindle nut is loose. You should not drive it until it's fixed.
Measure the caliper mounting bolt spacing. it is either 3" or 3.5" this will tell you what year (range) 911 the suspension is from. |
