Fit a Lexus. Is 200 master cylinder and servo. With slight adjustments to the location pin from the pedal arm. Fits directly. Note fitted to a panda where servo is on the near side. Unsure if it would fit in the off side position.

Using the standard. Brake layout & Pressure regulator.
But be aware of how the pipes connect a tee is required for the front wheels.
 
The fork end will require closing down to fit the pedal drive. Bar. Also the fixing centres are larger on the Lexus’s servo using 40x40 square washers to adapt available from Screwfix.to clamp to the pAnda fittings.
Note the front and rear outlets are transposed. Tee fitted to split front feeds.
 
As a lowly pandaneer. I believe it does as the master cylinders. Are not linked by a mechanical means. Fluid chamber. So the larger rear chamber created pressure when the front brakes. Start to resist the flow. The second chamber moves push ing the drums. This prevents the rearsxel sluing out. But it could also the rear restriction valve holds off the pressure until the front is resisting flow. I think.

Sorry no abs. System. Just to help with theory. Sv
 
Cool, thank you for the helpful thinking and diagrams.

In the cutaway you're right there looks as though there's no continuous piston. But fluid is incompressible so I think it's the size of the chambers that matters but they look the same..
I might try it both ways and see which one the MOT bloke likes best.

Started welding on some flange extensions for the mounting bracket today but ran out of gas.
 
Hey great. Adams got the same up grade to do. I did find the Lexus. Drawing for the actual. Master cylinder. But now lost in hyper space. Somewhere. Btw I do have rear discs too which may contribute to. The awesome braking force. Best of luck. Shame we haven’t done a distance time trial before and after.
 
We have fitted 2 types. One with. Stilo rear calliper
another using. Audi mk1 rear calliper. But both using standard front discs from the panda. Audi TT appears to be the best. For the position and handbrake cable operation. Both required a unique interface plate making. With longer bolts.
We do have GFX files for laser cutting if required. Steve
