Ventilated front discs
Hi,
Does there exist a ventilated disc for stock beetle calipers? I came across something on the net a while ago, but can`t find it again. Could be that they were cross-drilled, and this was advertised as ventilated though, as the disc must be very thin with proper centre ventilation. Also: what is the thickness of the Kerscher discs? The Talbot calipers I have can be used with somewhat thicker discs, like the type3, but perhaps also the Kerscher would fit. regards |

To fit ventilated discs(rotors) the caliper halfs need to be spaced apart to cater for the increased disc width. The CSP kit gives new calipers to over come this problem. If you are thinking of the CSP kit then its a little step to a full Porsche conversion.

I`m wondering if the Talbots would fit the Kerscher disc. Probaly not, but woudl be nice to verify it.
My current setup is Talbot front calipers, cross driller discs, type3 rears with 19,05 pumps |

The Talbot Horizon calipers were for solid not vented discs. it would be easy to check. Press the pistons back into the caliper body and see how much space you have between the opposing pistons, subtract the thickness of the pads + 0.03" clearance and vthat will give you the thickness of the disc. Then you will have to get all the specs of the CSP disc to see whether you will have to adjust the mounting position of the caliper.
Its all a lot of work and a bit hit and miss for no great benefit over what you have at the moment. Clive |

Hi
I tried to chase down some Talbot callipers a few years ago but had no luck. You could always fit a spacer inside the calliper where it splits to make it fit a thicker rotor. I've been told Porsche did this on some of their callipers. Steve

I wasn't sure if the Talbot calipers were in two halfs or whether they were a single forging that would preclude a spacer. If you are going down the route of a spacer then the mounting position of the caliper will still have to be checked and it would be a great opportunity to get some stainless steel pistons made for long term durability.

Hi
Some photos of the Talbot callipers. The spacers are not something you would do half-heartedly, you would proper skills or use somebody who does. Steve

This is a spacer kit that I found a while ago, for a triumph iirc but it shows what you need. In the end I went for the CSP kit.

Its all a bit of hard work making spacers up and then getting all that to work with ventilated discs that probably weren't intended for the application. You would only go with the spacers if the change to ventilated discs was easy as in the early/late conversion on the Range Rover Classic. If you wanted to go with vented discs I would think that it would be just as easy and cheap to select a vented disc caliper from the vast range now available that could have some corrolation with the disc selection.
Without pouring through the massive collection of discs the second option would be to machine some bells and then add competition discs and calipers such as AP, Willwood, Brembo whatever.. The wallet needs to be a little fatter but the whole reason behind the competition brake scenario was to be able to customise the brakes relatively easily. |
