OK so the front brake drums on my F20 have seized in place and the holes to remove have rysted out so I can't force it off with the screwing bolts into the holes thingy, apart from breaking the cast iron surrond and buying new ones does anyone have any suggestions on how to remove the offending item?

I don't supose you have a spares vehicle do you? Couse the easiest would be to split the swivle housing, and change the whole hub, half shaft, break asembly. Could be the ideal oppertunity to put later disk breakes on?
Other then that the only way I've done it befor way to use a long poll and a club hammer. Basicly bashing the drum off from the other side of the car. Poll under the car onto lip of drum, keep working your way round it. Being right out the other side of the car, rather than laying under it with a chisle alowes you to get a decent swing on the hammer.

Any veiws expresed in this thread by me are purely from my own experience, and (sometimes) falible memory. Hope my comments help, but please don't take them as gospel.

I had a whole F20 spare engine and everything! but my darling wife told me to get rid of it so I did!

I guess I will have to have a go at the other option.

Thank you.

Get a decent sized club

Submitted by bundyrumandcoke on

Get a decent sized club hammer, and hit the drum hard around the flat surface between the wheel studs. Spray heaps of WD40 into the gaps and holes around the drum. Then work it off with a couple of large screwdrivers between drum edge and backing plate. But make sure you hit it hard with that hammer first, to break the rust bond.

Front or Rear?

Submitted by Mace on

If its the rear drums rather than the front brakes, make certain the handbrake cable is fully released.A ridge forms at the drums edge and the shoes will not come through the drum - the handbrake holds the shoes close to the drum so they need fully retracting by slackening the handbrake cable. Fully retracted they will let the drum come away but might need a puller tool. Try soaking any access with pentrating oil. Then use a heat gun [do not use excessive heat]onto the centre of the drum and lever/hammer it away - puller tool is best.

thanks

I will give it a go with the heat gun, it is the front brakes though.

Braken

Slack the adjusters right off, on the back plate remove the brake pipe to release any pressure which may be holding the pistons out slightly.
Remove the mounting studs from the brake cylinders, rotate these carefully, or tap them down, this will free the top or bottom of the shoes, use the brake pipe hole, or the mounting stud holes. Damage may occur to the brake springs, but most likely these are shot anyway.
Using these holes, place a bar through to tap the brake drum, if they do not move, use a blowtorch to heat them evenly and slowly, this way you will minimise the risk of damage again.
Check the backplate for additional holes, these may also be useful access points, or simply an aperture for shining a light into the drum
Reface the drums using a lathe, and if they are to tolerance, you can re-use them after tapping new threads into the existing removal stud bolt holes.
