Any tricks for removing rear drums?
1989 Mazda 626. Tried to get the rear drums off, they wouldn't budge! The
manual said to pull the rubber plug and insert a screwdriver to put the spring retainer out of the way...there wasn't one. Then I remembered when I did a brake inspection a few years ago the retainer is on the OUTSIDE, but no joy. The drums are stuck. On Toyotas there is a rubber plug you can remove to loosen the adjuster, but not so on this car. |

I think the critical joint is where the inside rim of the drum rides against the side of the hub. What worked for me ('99 Cavalier) was - heating the drum right around the hub. I used a fair amount of heat, but just propane. While heating, I kept rotating the drum. - Between heatings, I ... - Pulled (hard) on the back rim of the drum (gloves help) and ... - Rapped the hub with a heavy hammer while pulling. Taking care not to whack the studs. Before that, I had done a lot rapping on the back rim of the drum, through a wooden block. That isn't what freed it, but who can say if it helped. Same with soaking the hub/drum joint with PB Blaster. Plus, using my 'power words'. Ears were burning in Chevy-land. G |

"stuck" as in frozen? does the mazda not have extractor screw holes that will force the drum off the hub? or "stuck" as in free of the hub, but trapped by the shoes embedded in grooved drums? in that case, you'll just have to break stuff - the drums can't be re-used anyway. -- nomina rutrum rutrum |

I think they're original. Only 201,000 miles. I already have new ones. |

Only 201,000 miles. I already have new ones. Are the factory flat head screws still attaching them to the hub? |

I had them off a few years ago to do an inspection, and all I remember is moving a spring stop, then moving the lever for the parking brake out of the way, and then sliding the drums off. |

I would think that there is a plug somewhere on the backing plate to access the adjuster. It is high on some cars and low on others. If the drum is frozen around the hub, an acetylene torch on the face of the drum just outside the hub may expand the drum enough to pop free of the hub. I anti-seize the hub where the drum fits over so it doesn't freeze again. -- Ray O (correct punctuation to reply) |

There are two JIS phillips screws in each drum face on my 1983 Mazda. I use a hand held hammer impact tool to loosen and remove them. There are two threaded holes that they will fit to pull the drum but I used two metric hex head bolts for better control. Bolts and axle hubs were sprayed with PB Blaster and drum was removed without having to back off brake adjustments. Axle end was also wire brushed prior to pulling drum. -- Mr.E |
