I removed the rear drum from my 56 reg 1.4 16v Peugeot 207 to replace a seized wheel cylinder. It's held on with a nut done up to about 200 ft/lbs. Having put it all together I just cannot get the drum to slide back onto the hub. It came off reasonably easily and I have cleaned it all up etc. Short of heating the drum and cooling the hub - any ideas or suggestions? Perhaps I am just not pushing hard enough? How hard can you hit these things?

ps it's not catching on the shoes, checked that. 3 x FL1 2 manual + 1 auto

Hard one that is but if it came off easy I don't think heating it up would help.

You've either upset the auto adjusting mechanism and over adjusted the brakes or there is a lip on the brake drum. If you're sure the brake adjuster hasn't been expanded and you haven't fitted new brake shoes (that are thicker) you'll find it easier to get the drum on if you bolt the wheel onto the drum first - it gives you a lot more leverage.

Edit: I see you're sure it's not catching the shoes (when you push it as hard as you can and it will go no further, can you spin the wheel?) so ignore that. If it's not going on you probably have a very small tolerance between the inner bearing and the stub axle. Again, having the wheel bolted on will make it easier to wiggle on. Get it on straight, push both edges of the wheel and wiggle! Past: FL2 TD4 HSE Auto

If it fits over the linings and the drum will fit over the hub if reversed then check the linings are the same width, there are options for the same drum diameter linings and some can be wider especially when buying via a motor factor, or if using the same linings they are not sitting correctly on the back plate. Measure the distance from the back plate rim and the depth of the drum. Fit it on the best you can and gently tighten the wheel bolts rotating the drum as you do so, if the drum stops or makes a sound you are catching on the edge of the linings or the new wheel cylinder my PC is slightly to the right of Genghis

In my frustration yesterday I took the shoes off and still couldn't get the drum to slide on. I am at the stage where I will be happy to pay for a garage to sort it out but I can't move the car ! 3 x FL1 2 manual + 1 auto

Is the bearing sliding over the stub axle?

OK thanks for all your comments, after lots of waggling and swearing it suddenly popped on. It's clearly a very close fit on the stub axle.
Now trying to decide whether to do the other side. I have done lots of brakes in my time but this one has taken the longest. Thank goodness for mobile phones where you can take a picture before you strip it down.

Incidentally I ordered a pair of wheel cylinders yesterday from Eurocarparts and since the order was over £10 they offered free delivery. Usual 30% off sale. I ordered at 1430 and they arrived on my doorstep at 1600 !  3 x FL1 2 manual + 1 auto

If its gone on now and spins easily, take it off again, adjust the adjuster a few clicks, refit and repeat until you can feel the shoes just touching. Always do it with the wheel bolted to the drum. Do this and you'll get a nice tight foot pedal and handbrake. Too loose and they'll be all sloppy. Personally, I get them just touching and (this is where some experience comes in) according to the size of the lip on the drum, give the adjuster a few more clicks. You will need to really wiggle it on though and it will be tight all the way right up until it is fully on, when you will be able to turn it. Careful though, too much adjustment and a lot of force and you'll never get it off again until the shoes have worn down. Plenty of smoke too! If you are handy with a hand grinder, you can carefully remove the lip then that takes all the guesswork out of getting a good pedal. Past: FL2 TD4 HSE Auto
