Seized rear drums

[Brabham]

Hi all,

The brakes have seized on one of the rear drums on my 2+2 as it has sat there for ages with the handbrake on. I gave it a bit of a whack on the front flat surface of the drum to try to free it up but no luck. Jacked it up and started to try to get it off by hitting the fins of the drum from behind using a big hammer with a block of wood so as not to damage the fins. Was coming off about half a mil at a time. Is there a better way?

Unscrew the pressure from the rear of the drum on your hand brake adjuster.

How long has it been since you had the drums off ???????

[peter t]

Undo the bleed screw to let the pressure off the brake cylinder.???? Just some thoughts to help maybe.

I disconnected the handbrake cable. Will check if there is any fluid in the system. The car has sat for years. Thanks Peter. Worst comes to worst it was coming off slowly by whacking it from behind.

Sounds similar to mine, drums never removed in 44 years. Sprayed heaps of PB Blaster via the stud holes and then hit with the rubber mallet. Took 10 minutes per drum.

You have wound back the brake shoes off the drums as indicated in the service manual?

All good advice above.

Does the engine run?

If it does, can you try jacking the car up off the ground and using the engine power to break the bond?

i recently had the same issue of seized drums on a pair of struts that were off the car. As they were not attached to the car, it was really difficult to work on them. I found the quickest way was to undo the stub axle nut and hammer the stub axle out along with the drum.

Do the drums have the two little threaded holes in between the wheel studs that you can use to remove drums by winding a bolt into the holes and onto the axle flange ? I can't remember if the alloy drums have them, or maybe alloy is a little weak for that sort of treatment - cast iron drums have them.

Mine did not have them, as you say the alloy is probably too soft.

Thanks guys,  will give it another go on the weekend. Andbir do you have a photo of where the adjuster sits on the rear left? Cheers

Here it is and a pic from eBay showing new cylinders with the lever you need to move to allow adjustment.

Also a image showing how to move the lever using a screwdriver.

Thanks for that, will give it a try

Thanks guys,  managed to get the drum off and it now rolls freely. Will be a lot easier next time!
