ok I think some of the published data may be wrong which has thrown out the calcs on the trend line as I know the original data for the 4 pots showed the only the area for the 2 of the pots.... based on 36mm pots. So as the data in the article is unclear as the title states that the PSI is load on one side of the disc, which but the SQ area is for all of the pistons (with the exception of the 4 pot which only showed 1/2 of the area it make the calcs meaning less. as I was working the force backwards as it wasn't included in the original data.

So basically as I the base data is a bit hard to understand... ignore me.

Sorry for making this all confusing I have deleted the posts...

Such things can happen.

We will work it out together and look at it from a critical point of view

"The 5/8" MC would be a good choice for brakepedal movement and brake control. "

Been searching on the net but I can't find the data on the size of my MC....

I'm at work now but when I'm home I'll check what kind of MC I have (hopefully it's somewhere on the MC) ..... If I got that size I will most likely be ok if I understand everything correct....

Can't wait to get home now..........

P.s Got an adjuster valve too, thanks to my work

If its a twin circuit Black tag it will be 0.70 both sides, if its a yellow tag it will be .075 for the front and 0.70 for the rear. the yellow tag cylinders have a 10mm and 12mm brake pipe connection where the black tags only use 10mm. or measure it

[Renessy]

Ok, been searching for a while to find out what kind of MC I have.

There weren't any tags on the MC but the fittings are both 10mm so that means there should be a black tag somewhere....

Anyway, I foud this: http://www.racing-st...r_cylinders.htm

If this is all correct it would mean that the MC is a 5/8" MC!!!!!

Everything will probably work out fine...... Will be a while to find it out because there is still a lot of work to do before I come to the brakes but now I'm able to sleep again at night.....

i no this is really really old, but how did you get on, did it work with the black tag split system. question for (René)

also could any one please tell me if they have used a yellow tag split system with a bias valve in the rear line.
i have metro 4 pot at the front an the new renualt handbrake calipers at the back.

or could any one tell me the best split system to use with the brakes i said i have got above.

any help would be good many thanks

I installed everything but the car isn't drivable yet so I don't really know if it works........ Still think it should work though.....

Though Mark, if find it a bit strange to hear that a 6 pot uses less oil then the 4 pots or metro brakes. How and where did you find that out???


Laters!

Well i measure the total piston area of the calipers?
Ie, KAD/Metro 35mm diameter x 8 pistons (962mm squared x8 = 7696mm squared [Total piston area])

--------------------------------------------------------------------------------------------------------------------------------------

Tarox 6 pot
30mm diameter pistons x 4 (706mm squared x 4 = 2824mm squared)
26mm diameter pistons x 8 ( 530mm squared x 8 = 4240 mm squared)

2824 + 4240 = 7064mm squared (Total piston area)

Does this make sense now??


Cheers

Have i missed something, surely it should be x12 as there are 12 pistons not 8?

ok thanks any more information would be great from any one who has a good front to rear split working system

8+4 = 12 the pistons are not all the same size.
