Perentie brake adjustment

[charlie a]

The brake pedal on my 4x4 Perentie does not become hard until it is about 3/4 depressed. The brakes won't "pump up" like they would if they needed adjustment at the back wheels.
The brakes actually work quite well otherwise.
I have recently replaced the the rear brake shoes, being careful they went in the right way, and adjusted them.
I strongly suspect the adjustment of the push rod yoke where it joins the clevis pin on the brake pedal assembly.
Is this the only adjustment in the master cylinder/booster area and is there something else I am overlooking?
Thanks for your help.

Are you really sure you did the drums correctly? It is easy to get them wrong.

Beyond that you probably have air in the system or a bad master cylinder.

Has the peddle always been like this? If not then I would say that it is the drum sdjustment. If the springs and pistons in the rear drums are in good shape they will not pump up much because they will be returning to their resting position quite quickly.

If the peddle has always been like this then perhaps the peddle/master cylinder has not been set up correctly. Or there might be some air in the system. I use a vacuum fluid extractor when bleeding the brakes myself and it makes if really easy to do.

My brakes were always like that till I had the booster overhauled .

Some years back I had a similar issue after replacing the drums. Fixed it by replacing the RH new drum with another new drum that had the braking surface more accurately concentric with the centre hole.

Without being able to look at it, I'm also wondering about the booster or the vacuum line.

Does the vacuum build up after engine starting in the usual way ?
