The bearings I used are two SKF 15x28x7, part number 61902-2RS1
For the tube I took a stainless steel tube with 15 mm outer and 13 mm inner diameter, shortened to a length of 21 mm
In addition, the following tools are required:
- 28 mm Forstner bit to prepare the bearing intake
- 13 mm tenon bit to prepare the axis
- lathe to prepare the fit of the tube
- drill rig and a cross table to perform accurate bored holes
and you need experience in working with this tools.
You see, there is a lot of time and precision work required.
But you're right, the most important is to remove the plastic brake shoe.
With this sole change you get the whole new feeling in gas pedal,
it seems crazy but it's true.
My experience of driving without the brake shoe for over six month showed the throttle response is predominantly due to the gas pedal assembly.
I am very interested about your experiences with this modification and hope you can share my assessment.
