I just purchased a new aftermarket Master Cylinder off Ebay that looks identical to my original. I found that the push rod and rubber bushing slide into the piston with no resistance and will easily pull out. I checked with t a caliper and the new piston inner bore is the same size and the rubber busing. Also, there is no machined slot inside the piston bore. I contacted the seller and he said he sold 77 of these with no reported problem. Also, I found the piston retainer with rubber sleeve mounting holes are now metric. The loose piston/bushing has to be a safety issue being the brake light switch would be the only thing preventing the push arm pull out. Has anyone installed a manual MC without a secured push rod bushing? Is it possible the power brake MC can use this? I wanted to run it past the forum experts. Thanks
