I’m working on the front S calipers on the GT build and hit a snag.
The pads do not seem to be for this application. Wondering if different pads are warranted. I know these Porterfields have more meat on them. That could be the reason. The pistons are seated all the way in. (Fresh rebuild). I even tried moving them with a wooden dowel. They budge just enough to collapse seal slightly but when relaxed sit as they are. Am I doing it wrong? (IMG:style_emoticons/default/dry.gif) Help appreciated!! Note: no fluid in system yet. Any brake pad recommendations? Pics Attached thumbnail(s) Attached image(s) |

Are you sure you have the right rotor paired with those calipers? Looks too wide.
Not much space between the rotor and the caliper housing to account for lateral hub deflection. A bit hard to tell what the gap is between the rotor and the caliper housing from the photo's but looks tight. A rotor that is a couple millimeters too wide would explain why the pads don't fit and would need pad compound taken off to fit. If rotor is correct, I'd machine off pad material before I took off the backing plate noise isolator. Regardless . . . go with whatever Eric chimes in with. |

Phil the rotor is one that was recommended for this set-up. I’d have to find the box for specs. Thanks. Hopefully Eric may chime in. Thanks Brent for alerting him :-) |
