Thread: 11" front drums

Ten inch can be unpredictable when they are wet so I don't think the problem is just associated with eleven inch brakes, although as they assumedly have better stopping power it may accentuate the problem.
If all you need is drums I would be sticking with the eleven inch conversion.
You can always change them back to standard ten inch down the track if you find them unsatisfactory.
The eleven inch conversion is/was popular with short wheel base Land Rovers repowered with larger engines.


Cheers, Mick.

Cheers nick, next question is.. Where can I get some 11" drums from that won't cost me 200 each?
And what other models did they come offoff?

Rear or front of any 109 4 cyl s2 s2a or s3 maybe some very late s1 109.

Careful when sourcing drums - they come in two widths and two different wheel stud sizes check to see which you have. (Since it is a conversion, it could be off any Series Landrover!)

The narrower drums were fitted to all Series 2, 2a 109, and Series 3* 109 and 110/Defender*. The wider drums were fitted to Series 2a & 3 109 six and V8 front. Also fitted to all Series 3 109 in late production.

The applications marked * are the same as Series 2a except that these vehicles had larger diameter (16mm vs 7/16") studs (as did the last of Series 2a).

The Series 3 drums can be fitted to the narrower studs if you have made collars to fill the annulus left round the studs. The studs take the braking force - don't rely on the small countersunk screws.

Hello from Brisbane.

Following John's advice re the two different widths of linings on 11" brakes be also aware that the backing plates are also different between the two types. The plate on the wider lining type (3") is offset inwards to keep them centred on the wider drum.

So, I would be trying to identify what is fitted to your truck already before getting too advanced in sourcing drums.

I know your front drums are missing, but in case you can't recognise the difference without a tape measure, the 11" x 3" drum has a 'square' shoulder which is different to the 11" rear drum on any 109" or the identical narrower 11" front drum off a 4 cylinder 109"which has a rounded shoulder.

Cheers,
