First of all I have to say thanks to both Amzimmy and Fernweh for their help getting the components. Karl sold me a set of rebuilt calipers from his spares only to find out that they were not right for my machine. Instead of just getting them back he found the correct ones in Germany, and found a very creative way of getting them to me. Thanks Karl and thanks again to the "courier". Michel, I am still unclear about how I have these beautiful rotors but Thanks Again and I'll leave it at that! I was very interested in improving braking on my '85 300GD. I was looking for pads and more interesting rotors as well as rear shoe compound choices but nothing was coming to the surface. I bought the calipers from Karl because I felt that there was a problem with the stock ones and my thinking was I would install those and rebuild mine and have a pair on the shelf. Then Michel came through with these rotors. They are beautifully made, each set has been checked for correct specs and the detail and materials are remarkable. There are built in wear and temperature indicators and they are slotted. They are a Perfect fit. I mean really perfect. My brakes were ready for pads but I had and intermittent pull to the left under firm braking. This is never good in a left hand drive environment and things have been snowy, icy and wet. So I was able to find the time to get them on the truck. (The big vineyard is under 2 feet of snow and so is the winery in Mac). First impressions are a very different and firm brake feel. I am amazed. They need to be broken in with care but it is obvious the rotors are a very big improvement. Powerbrake supplied them with Jurid pads. I decided to go with those. I will let you know how they work as they get used. The calipers cured the pull. -Dai (stockbrake.jpg) (caliper:rebuilt.jpg) (rotor:stock:Powerbrake.jpg) (rotor:caliperinstalled.jpg) Attachments ----------------  stockbrake.jpg (108KB - 0 downloads) caliper:rebuilt.jpg (91KB - 1 downloads) rotor:stock:Powerbrake.jpg (72KB - 1 downloads) rotor:caliperinstalled.jpg (99KB - 1 downloads) | |

Forgot to give a link: http://www.powerbrake.co.za/tech_info/tech.htm The articles are well written. I think Michel is really happy with his set on Muffetta (300GD+). I found bleeding the dry calipers to be tricky. The most difficult is the inboard piston bleeder (lower solo bleeder). I just could not get all of the tiny air bubbles of air out of there (on both sides). This was using a pressure bleeder and my son Boone doing the classic brake pedal routine. I have a rock solid pedal but I will go back and bleed again after some miles. I put some more miles on it today. Smooth and straight. Excellent feel, I can't wait so really see what they can do. -Dai Edited by dai 12/25/2008 2:23 AM (padview.jpg) (powerbrakeG.jpg) Attachments ---------------- padview.jpg (84KB - 0 downloads) powerbrakeG.jpg (88KB - 1 downloads) | |

In addition to Dai's picks, here are my rotors that I have fitted some time back. They have done about 100 000 km and are still in perfect condition. I think that, as Dai mentioned, the correct marriage of the rotors and the appropriate pad designed for the application and materials, is the key for long lasting and efficient brakes. Powerbrake does supply for a wide range of cars and racing cars too. They will supply and send their products world-wide. Dai, to simply answer your question "why?" , well you were in need of new front rotors and what better way to thank you and your family for your warm hospitality!!!!! amzimmy  Edited by amzimmy 12/25/2008 3:38 AM (DSC01364.jpg) (DSC01365.jpg) (DSC01368.jpg) Attachments ---------------- DSC01364.jpg (145KB - 0 downloads) DSC01365.jpg (132KB - 0 downloads) DSC01368.jpg (117KB - 0 downloads) | |

Tjærand, it's very easy get someone in Germany or even Switzerland to import them for you and then send them to you. Has been done before! amzimmy | |
