disc brake conversion
« on: February 06, 2011, 07:32:11 PM »
hi all
i am looking at changing from drums to discs at the front. after a bit of research it appears there are 2 options on the market. the chinese version and the other. i was wondering if anyone has fitted the chinese version and if they have any probs. seems there is quite a price difference.

Hi,
i dont think money should make a differance when it comes to brakes..
its all about quality.....
For me.....I will never take a chance with cheap quality brakes because your life depends on it.
So forget about the cash and choose teh better set...
if you need to save a bit longer then just wait until you have the best...

Hmmmm i would be curious to see these other disc brakes...

http://minisport.com.au/prod1588.htm

is the 7.5" cooper s disc conversion, amazing value for $1200! not really worth putting a value on something that is used and abused every time that a car is driven... i, just out of principle wouldnt buy the cheaper chinese version, i cant imagine my brakes failing (again... yes it has happened to me before....)
Sure a set of drum brakes will stop you better first time (that is due to the amount of pad on the braking surface)

BUT

disc's with some EBC green stuff pads will suffer little to no 'fading' due to heat transfer unlike drums...

On another note, just remember to change the wheel cylinders to accommodate for the higher pressure needed to clamp disc's...

I presume your talking about Moke Aust,when you say they have no stock......
If it is them your talking of, I know 2 people who have replaced there drums with these...one has them on for over 6 months, and is very happy,except he said the Pads don't wear well
the other for about 3 weeks and no complaints

No probs there, 8.4's are usually cheaper, good value, minimum 12-13" wheels are needed.

Alot of the wheel dealers from the 60's/80's will tell you that you cant go past the 7.5" cooper s conversion... 6 of one, half a dozen of the other.

Booster will mean tougher pedal, but more responsive.... you'll have a great right calf in a few weeks  ;D

are the 8.4 all vented disc's like these ?



which is a lot better for braking as they loose there hot tempetuur a lot quicker.
which in its turn have less chance of becoming worped.

We have mini metro turbo discs on our moke, tuned down to 7.9" cause we run 10 inch wheels sometimes when doing motorkhanas. We dont run a booster, and it stops bloody hard.

-1977 Moke (1310,40mm weber,8.4'' discs, Graham Russel cam, Quaife LSD)
-1971 Moke (bog standard 1100 and comes with free RUST)

Care to elaborate Matt? A booster is there to make the braking easier. It works by converting the enegry from the vaccum of the intake manifold into positive pressure within the hydraulic system and hence, makes braking easier....or perhaps thats what you meant...

Vented discs are indeed designed to dissipate heat faster, and they do their job well. Dont waist your money on slotted as slotting is designed to remove dust and gas under very heavy nd constant braking however, let's face it, this would never be necessary on a road going Moke. Slotting is designed for track use and would offer little to no benefit on public road systems with speed limits.

You may want to check with the local regulations on that. Some states require boosters (aka. servo's) to be fitted to Mini's/Moke's with disc brakes. The common VH44 booster is what most people opt for these days.

You will need to fit 5/8" (from memory) slave cylinders on the rear so as to prevent your rear wheels from locking up.

For interest sake, you may like to read about possible custom options which can arguably work out cheaper or around the same price and when engineered correctly with, much greater efficiency. I have some writing on my setup here: http://www.minimoke.net.au/rest_brakes.htm - apologies for the slowness of the site....ill get around to migrating it over to Joomla or Liferay one day....

Also for interest sake, you can see the location of the booster I fitted to my Moke here:


I have heard of others mounting them in the side box next to the driver which wouldn't be a bad spot so long as your vaccum hose is long enough to reach from the manifold through the side box.

Cooper S 7 1/2" disks are not  much better than drums on a 13" wheel moke and they cost too much, leave them for the Minis and little wheelers. There are several options of 8.4" disks or greater. I have unboosted metro 4 pots and ventilated 8.4" disks on my current Moke and they are excellent. I outbraked a modern car and nearly got tail-ended during a sudden stop in traffic last week. The standard non-ventilated two pot calipers are still very good, and a lot cheaper, especially if you can get a decent secondhand set.

I know very little about the Chinese ones, but aren't they single pot sliding calipers? That style is generally less well regarded, they have a tendency to stick in dusty or muddy conditions.

Hey Pre10der, looks like you only have boosted fronts, not the best for balance, but the rears don't do much anyway. Ever thought about a booster set up from a Rover Mini?

I would have to agree with Tim on the Cooper S (7.5") Discs on a big wheeler. Bigger wheels means more leverage, needing a bigger diameter disc.

On those Chinese Discs, I haven't seen them but if they are a floating caliper - YUK!
