What rear brakes to use with front discbrakes ?

[Rasser]

If I were to install either a CSP front disc brake kit or a airkewld bad brake front disc brake kit, what rear brakes would you guys prefer ?

Facts about the car:
5x205
4,5" BRM front with 135R15
5,5" BRM Rear with 185R15
2" narrow front beam with CB dropped spindles
Short axles.
callook stance

I have backingplates for the following models: 30mm T1 (5x205 std. drums), 40mm T1 (4x130 std. drums), 46mm T3 (4x? std. drums).

I am now running std. 30mm drums in the rear, but want´s better braking in the rear. I would also like to have each rearwheel moved about 10mm closer to the fender (track increase).

What choice do I have if I still want to keep the short axles and the 5x205 bolt pattern ?

All help is well appreciated...

Thanks /Rasmus

Ah, thanks almost the same question for me i'll keep a close eye on this thread

I'd say type 3 brakes all the way

why don't you just take the whole csp kit -front and rear

What if you use the later backingplate with 40mm shoes and these drums?

They are for long axles.... I have short.



Does Anybody know how wide the T3  5x205 drums are ?  (CSP has these as well)

I thought it was enough to machine down the snout of the drum a little...?

[Type1/DVK]

Please note a track inscrease of 2mm per side.

That should be the machining Rune, isn't it..

With the good backingplate it should fit right?

if you´re running std. 40mm rearbrakes on your 68 later T1 then adding the 5x205 aftermarket drums that csp sells, will increase the track 2mm per side.
And this is with long axles!

I don´t know if it is possible to machine the drums to fit short axles - but it doesnt look like there is that much material left before the drum.
Off course if you want to use this CSP 5x205 40mm wide drum, then you have to use the backingplate for the 40mm drums.

I would really like to have 5x205 46mm brakes in the rear.... or if this can´t be done then I will settle for the 40mm drums, but I wont compromise on the short axles or the 5x205 pattern.

But does anybody know for sure what can be done - and what the exact track increase will be ?

tobi/DFL's got the csp rear brakes on short axles -i think he just twisted off a bit

Thanks a lot.

Any idea about the offset ?

i know it can be done on later drums of a type 3. they have a seperate center that goes ove the splines. the drum itself is a different part. the earlier types are one piece, but i have to check if they hada different axle. the later ones have long axles and if you fit short ones you can macine them down a bit. there is an article in vwtrends about it if i remember it right.
by the looks of the early drums they can be machined as well but i am not quite sure if it is enough...

hope it helps a little. but i guess csp disks will work better.

Hi Guys,

I have a 65 Notch. The car runs on wide 5's as it is an early type three.
To get my wider tires to fit, I swapped to short axles, aka pre 65 type 1 axles. I kept the original rear drums but needed them to be machined to be able to fit the axle nut properly.
So if you want to increase the braking power on your ride, I would go for the early type 3 brakes in the back combined with the CPS disk up front. I have a set of these fine brakes fitted as well. Be shure to fit a brake mastercilinder for dual circuit. I've tried to retain the original single circuit mastercilinder but brakingpower was not good, so I swapped to dual circuit and have been using this set up for over 20k and still very happy with it.
My other ride, a 86 bug had og-disk brakes up front and a late type 3 brake set-up at the rear which worked fine as well.

very interesting argument… I would think..  on front to put  the kit of the CBperformance
http://www.cbperformance.com/catalog.asp?ProductID=1140  and to the posterior one I would want to leave the original drum brakes of beetle rag-top 1963? I could have problems?

When you have short axles and type three or 68 and later you just machine 14 mm of the snout of the drum. I have a 67 that runs on both 4 and five bolt. If you have a problem with type three drums being to wide you can machine of some material on the inside of the drum to compensate for the increase in with for the type three. If you look at the picture of CSP 5bolt drum it is easy to see that 14mm is no problem.
