TR2/3/3A Installation of rear brake cylinders for 9" brakes on TR 3A.

[John_Progess]

I am trying to install the rear brake cylinders on 9" brakes. The cylinders are secured to the brake back plate with a retaining plate, spring plate, a distance piece and a dust seal. I cannot get all this installed on the cylinder when it is off the back plate and with the back plate added there is not enough clearance. I can get the retaining plate and the spring plate attached to the cylinder and the back plate but not the dust seal and the small distance piece. It is very snug just using the retaining plate and the spring plate. Am I missing something? Thanks and have a good day!

Picture? It is tight, but far from impossible if you have the correct parts.

John,
you just need more perseverance. Also a small hammer to tap in the middle plate between the top and bottom plates. The rubber cover fits over the whole operation and tucks itself in under the assembled sides very nicely. No room needed for the cover between the plates.

Many of the diagrams show the retaining plates in the wrong orientation and/or wrong order, making them almost impossible to install. There are 3 plates involved, a smaller one and two larger ones. One of the larger ones has small tabs that stick up from it, the other does not.

Start with the handbrake lever not installed. Insert the smaller plate with the opening facing away from the handbrake lever and the tabs away from the backplate. Then the larger plate with the tabs goes between it and the backplate, same orientation (opening away from lever, tabs up).

Now you should be able to slip the handbrake lever into place under the end of the cylinder.

Last operation is to tap the remaining large plate into place between the first two, with its opening towards the handbrake lever. Keep tapping until the tabs on the other large plate engage with the notches in the plate you are installing.

This process is written up in the TR3 supplement to the TR2/3 Workshop manual. The illustration is wrong, but the text is correct.
