M809 - Rear Wheel Cylinders in the Front?

[Speedzilla]

Hey Guys,

I was servicing my M816, and I noticed that one wheel cylinder on the front was a rear (2") and one was a front (1 3/4") - Has anyone seen this done? Any advantages or ill effects to be known? Don't have another front cylinder to throw on right now. Thanks!

Mine had 2 " on the front no problems back in the day we could not get the 1 3/4 we used the rear cylinders. If it is on one side maybe a slight pull but doubt it? See who else chimes in

Its a proportional thing. I would put a 2" cyl on there, but it will still stop with out it. I sure wouldn't want a smaller one(than 2") though.

I would use both the same and if the 2" work without problems stick with them, the only difference I think you will notice is the front brakes won't start applying sooner than the rear which is probably why they were setup this way. Okay bring it!

When we restored the "restored" m62, we used rears on the front, for the main reason if a wheel cylinder took a dump, we only need one size on the shelf.

USE 2" cylinders. The front braking effort on (ALL) vehicles IS more proportionally biased to the front. (as) the Front of a vehicle takes the most load Caused by Weight transfer.
As this weight transfer progresses less braking effort is required on the rear wheels.
LESS braking effort to the rears prevents the rear wheels breaking grip as this transfer occurs.
(think) MOST trucks and many cars have a BRAKING EFFORT LIMITER on the rear axle. (some have Load sensing limiters).
YOU DO NOT want unequal braking effort across the chassis on the front (steering") wheels. (do you!?)

SAFETY FIRST>>Actually I am genuinely concerned for you ( yours( and other road users )). Please rectify those brakes before you (have to) carry out an emergency stop. DON'T even THINK WET!. BE SAFE.
