Rear brake caliper CSR from VAG to Hispec wheel speed sensor

att. some pictures of my modification. I wanted to have a lighter caliper and one who fits well within a 13" rim. Before I sanded off the rips of the  original Volkswagen caliper to fit into 13" rim but this was not satisfactory for me. The pad is a Ferodo FCP809H its 45mm high and covers the max. possible diameter of the disc. The handbrake has the short levers for the pads and is not so effective as the one with the VAG caliper. I made the mounting holes M10x1,25 myself. The handbrake cable is different than the original one so I used 15cm from the original one to maintain the adjustment possibility. Did drive now 1000 km and everything works well. Pedal feels firmer than before.

I also modified the wheel speed sensor to an hall effect sensor for connection the 9A9 MBE. Sensor is a GS100701 ad a new sensorring Maxgear 27-0319. I took off each 2nd tooth of the ring to be close in line with the sensor specs. sorry  for the pictures turned to the side.

Well done Hanns Per. I like your solution. I may go this way in my CSR adaptation to 13" wheels. How did this conversion affect the brake balance front to rear? How did you splice the handbrake cable?

I cut off from existing handbrake tube (spiral housing) approx. 20cm for the use in the adjustable link (in my case on the lefthand side). From this piece I removed the inner  PET tube with a long driller. The remaining part (spiral heavy wire) I put over the inner PET tube of the Hispec handbrake tube. I could pull out the inner PET tube from the Hispec handbrake tube. where the 2 tubes meet I used a heat shrink tube with glue to strenghten and secure the connetion. Hispec handbrake cable and tube comes in 2 parts. hve now some experience , did not notice a problem with balance yet. Only downside is the weak handbrake brake performance also due to the shorter lever on the caliper hadbrake levers. If You want more info I can call you BRGDS Hanns Per

one more thing has to bewatched  the caliper bolts on my CSR are 10x 1,25mm and  the VAG bolts seem to be 9x1,25mm
