| Post subject: | chewed out drum brake screw removal |
G'day guys, I've got a chewed up screw head on one of the drum retaining screws on the front of my 850, i've tried tapping at it with a small cold chisel to try and get it to free up but she's not budging readily. Has anyone got any ideas thats has worked before, I've thought about MIG tacking a nut onto the screw and undoing it with a socket and ratchet? any pitfalls to this i should be aware of?? Thanks in advance. Pete |

The easiest way is to drill the head off the screw and then remove the drum and attack the screw with vice grips and Penetrene® |

Impact screwdriver. Best $5 I ever spent, many moons ago. But if the slot is totally gone I'd do what M1100 said. |

I know someone else who swears by those too.. he was restoring a 911 and reckoned it was the best tool ever. |

I have one with a 1/2'" drive so you can stick sockets on it too |

Thanks for the replies guys, I initially tried the impact driver and thats what chewed the screw head so I got a drill onto it and drilled the head off, removed the drum with a touch of brutality and now have to finish off the rest of the screw. I noticed the drum is dated 2month 62.......surely it can't be the original drums? there was plently of lining left on the shoes but the lining has separated. Here's a pic of the drums

By the way my 850 was dated using the register as a September 62 build. Still only has single leading front brakes too |

I wouldn't be surprised... they didn't go fast enough to use enough brakes to wear grooves into the drums there would be lots of unrestored cars getting around on original drums |

I wouldn't be surprised... they didn't go fast enough to use enough brakes to wear grooves into the drums there would be lots of unrestored cars getting around on original drums I'm not surprised many cars here have old drums still. Remember that here in Oz, brake shops remachined these 7" drums when worn, first to + 1/32" then to +1/16" diameter. They then bonded oversize linings to the shoes and radius ground them to the right oversize. But in UK, I think they just tossed the drums when worn and fitted new drums and shoes. Parts then were much cheaper and more available there than here. |
