Kerscher Brakes/Boxter Calipers

Post by fastback »

Hi
I have Kerscher brake system fitted om my Type 3 .
Vented disc's in front with Porsche Boxter 4 piston calippers and disc brakes in the rear.
I also have a larger Masterpump from Kerscher.
But..
I have a schematic of how to hook up the brakelines from another kerscher set with 2 piston calipers.
There ,the rearbrakes is conected to the "Front" output of the Masterpump and the frontbrakes to the "Rear" output.

Is this correct with the larger boxter calippers also?
Or must i have the other masterpump that is on the kerscher website to get it work properly.

Anyone know the reason for why the brakelines are hooked up this opposite way??

I have the same set up and purchased the kersher master cylinder as well. I don't know why they show the brakes lines hooked up in reverse either. The master seems to be the same piston size for both the front and back circuits. BTW- maybe just bad luck but I was never able to get a decent brake pedal with the Kersher MC and ended up using a late model bus 20 mm MC. The other problem I had with that MC is that the collar sticking out the front of the MC is so long that it interfered with the brake pedal push rod.

Have you checked the MC for different piston sizing?
I posted a thread on the Germanlook forum and he claims that the MC i have has different sized cylinders.

I think Lanner's explanation is very reasonable. When I took the MC to my local shop they looked up the part number as a Golf MC and they thought that the MC was same size front and rear. They might be wrong. I know it's a major pain in the neck as the rear brake line is too short to reach that front part of the MC so you would need an extension of some sort.

hello,
im considering buying the kerscher vented disk kit but with the 2 piston calipers (i think) for my bug.
could i ask a few questions:
- are you happy with the quality of their kit?
- how do you rate the stopping power? (i may go for the early 944 single slider conversion)
- do you know where i can get any other information about the kerscher kits as the website is in german and i dont understand it.
thanks,
mabbo

Typical German high quality. You will be happy with it. The stopping power is good enough for a mildly modified Bug. Use with their 20.6mm master cylinder to get the best result (CSP have one for RHD)

You can check out CSP website
www.csp-shop.de
I think the one they sell is the same as that of Kerscher. Or you can use AltaVista to read Kerscher website.

One thing still mysterious to me is the brake pads. Anyone knows which make of car are the brake pads from if I need to buy replacement pads?

hey dude,
thanks for the reply... my bug has quite a powerfull engine (well, it is when it runs!)... its a 1955cc EFI Turbo... not the all out fire breathing monsters some people have, but its a hell of a lot faster than my old 1776 ;)
so i was going to go for the early 944 front calipers/disks/hubs etc but i dont fancy doing all that machining.
do you think the early 944 option would be better than the kerscher kit then? i dont want to go too big because i need to keep 15" wheels.
thanks

Wow! How about Wilwood Powerlite 4-pot calipers? No problem to fit under 15" wheels. You can use them with Kerscher front vent discs (278 x 20mm) but you need to fabricate mounting brackets. It may cost less than the 944 setup considering that the machining and restoring costs for the old 944 parts are not cheap.

I think you need the rear disc brake too.

Another Wilwood option, if you already did the 944 spindles..

If u mean the 160HP kit from kersher , the calipers arejust stock ones that are widened , due to the wider vented disc, so stock pads should fit.

i also tore the label off the Kerscher MC box and looked up the part at ATE's website.

Under Parts search i found it

The MC is from a Renault Traffic BUS...
Ø: 20,64 mm

but does not say anything about different sized pistons
