Front Brakes on Rear ?

Postby PSL184 » Thu Oct 30, 2008 11:48 pm

I will soon be fitting Wolseley front brakes to the Mog and as the original fronts are all new I was thinking of fitting them to the rear.... Anyone done this or forsee any pitfalls at all?

How will you connect the handbrake cables to them?

If it doesn't work, you're not hitting it with a big enough hammer.

Use standard rear cylinder as one of the rear cylinders?

Do you mean you are fitting just the front shoes to the rear or the whole assembly?

Would probably be much easier to fit a set of Wolseley 1500 rear brakes if you can find a set.

Yes but finding them is the problem! I know someone who has a rear axle but I doubt they are selling it.... I won't mention any names, David :-)

is it worth it at all? with disc on the front where all the weight is then you really don't need a rear brake upgrade

I'd leave well alone and sell on the front set as they would be worth it to someone facing a rebuild

I have thought about this conversion - but the rear brake backplate is quite complicated, and so only way I could see to do it is to cut the centre out of a normal rear backplate - and weld it into the centre of the front brake backplate! Then - modify to take the normal rear cylinder and of course the piviot point for the other end of the shoes. Quite a task! My old Rally Minor did have Wolseley rear brakes and they were fantastic - handbrake turns with ease!

the rear brake needs one leading and one trailing shoe - this allows the handbrake to work efficiently in BOTH directions.
Therefore not much to be gained by using front brake kit on the rear apart form a lot of hassle.

Yes, similar to my thinking Roy... Would you use single cylinder?
Rob, I see where you are coming from but brake balance front to rear is just as important as side to side AND I have to have something to keep me busy over the winter :-)

Yes - the single cylinder with the handbrake lever - just exactyly as per normal rear brake but with front brake drum and shoes (mounted leading and trailing) and that modified backplate. I've got all the bits, and the idea - just need the time !!!!!!!!

Ray, I don't see how a trailing shoe on the rear improves the handbrake :oops:

Why bother! - sell the good parts you have and make sure your rear brakes are working properly, the handbrake should be good enough to lock the rears.

it gives you a leading shoe forwards and backwards - so doesn't matter which way you park on a hill.

Yes - if both are 'leading' they will be hopeless on a hill!
Reason for larger brakes is to get a better balance with the better front brakes (be they disc or drum). But this may possibly be achieved with (say) Marina rear brake backplates or something similar - as long as Minor hubs/8" drums/half-shafts can be used ??

Hmmmm Marina 8" rears... Yes possibly a time saver. I'll look into it!

It may work if the sealing arrangement to the axle tube ends is the same! But I would say it's a long shot.
