Thread: Front brakes dragging

Tweet

I agree with you on the import parts issue, however I have not been able to find any made in the USA 8” dual boosters, I rarely see any parts made in the USA. Where would you purchase a booster that's made in the USA? I'm certain that there are a limited number of Chinese manufacturers so buying parts anywhere is a luck of the draw.

Yes I triple checked the pushrod clearance, I even went so far as to leave an extra 0.040 clearance. I bench tested the 8" booster and the pushrod on the master cylinder side would not retract completely when released, the dragging brakes got worse as operating temps increased. The dragging issue was erratic and was definitely related to temperature.

I think the secondary pushrod on the 8" booster may not have been lubricated properly when assembled causing it to hang when retracting, especially when hot.
