Brakr Rod Conversion continued.
Brake Rod:
1. The brake rod in stainless steel can be purchased from Lightning Spares.
2. Assemble the brake and Z Arm into position, measure the length of rod that is required to the connection point on the Z Arm.
3. Grip the brake rod in the vice protecting it with wood and then form the elbow with a hammer.
4. Cut off the excess rod of the elbow and drill for split pin.
Note: If you file a very small flat where you want to centre punch it will make it easier to centre punch in the middle of the rod.
Hints:
1. Check dimensions, from centre of the crossover shaft to the top of Z Arm 3.1/4’’ (83mm). Overall length of top part including rod bracket 2.1/2’’ (63mm), again this for a 1962 Super Rocket, could start off with pipe to long and cut to length as required, but make the arm as short as possible the longer it is then the more travel on brake pedal.
2. Check before painting on the Z Arm you may needs to remove some of the pipe as it may foul the swing arm main nut.
3. I used Hammerite Smooth Spray 4 coats gave it a nice deep shine.
4. Main problem I had when I took the crossover shaft arm off, the brake pedal spring slip come off its mount, I struggled to get in place when reassembling.
5. There is also a modification to the rear brake pedal that you may wish to consider while do this work, my Super Rocket come with this mod done.

March 2013 update:
Photo: Showing Z arm with clevis fitting by A7 – A10 Forum Member
As you will see in this photo a clevis has been used to connect to the Z arm.
Clearances to the oil tank and pipes would need to be checked if using this
method.
Also one of the Forum Members has used a the ring part of a combination spanner to make the brake arm, this method will give more adjustment which is a very good ideal.
