Handbraking rear wheels individually?

Oh dear!

30 years ago every single thing in the world was better and made properly. Now everything is made in China out of pencil eraser rubber and old Dinky toys, I bet they won't last a week before something starts leaking....

Right back to the start of this thread, yes it's easy to do with the handbrake cables and it works a treat. I just need to cut the original lever handles off and make detachable ones at the right angle. I'll post photos later , they're on my old phone

Now, bear with me as I am going to use the words "if" and "might" a lot here! And this may well be just a pipedream, but while I am daydreaming it may be worth a check...

I have ABS, so was wondering if that gave any other options. If the ABS module is on CAN, K-line or similar, then it presumably has fault codes and might have diagnostic routines. If it does have diagnostic routines, then it might allow us to control the valve to each wheel (useful for testing in manufacture and service maybe?!?). I assume the module is braking only (i.e. not used on any traction control models anywhere), so it can only block the pipe, and not actually apply any pressure of it's own. So, if the valve for any one wheel could be closed via diagnostic routines, then you could, while stationary, push the footbrake, lock the relevant valve and now that wheel will stay locked until you release the valve. The rest of the ABS valves may not work if this mode even exists, but that won't be an issue in these circumstances.
If all of the above were miraculously possible, then we could have a separate controller that plugged in to the OBD port, and invoked the valve routines as needed (one button per wheel), so we could plug it in only when safely off-road, leaving the car untouched at all other times... My understanding is that the rear brakes are both fed together, so this would only really work on the front wheels, but, hey....

That is a lot of "ifs" and "mights", and is about as Heath-Robinson as it comes, and I have no idea how to find out about potential internal test routines of the ABS module, so my first question is whether anyone here knows anything about the ABS module (mine appears to be made by ADVICS, but that is all I know so far)? The service manual mentions "Serial data line (K line of ISO 9141) (3) is used for SUZUKI scan
tool or generic scan tool to communicate with ECM, TCM, Air Bag, SDM and ABS control module.", but does not say much about what the scan tool actually allows you to do. Does anyone have any more details about the tool and/or it's supported functionality?

I suspect I have missed something glaringly obvious - please feel free to point it out

Thanks Johnniehec - that crossed with my ridiculously-complicated last message, and sounds infinitely simpler! Pictures would be great

Here are some photos [at ]

Hi Johnniehec,

Unfortunately, the first three of those photos did not come through. The triple handbrake lever did, and some tantalising shots of brackets, but not the ones that hopefully tie it all together
