Morris Minor Owners Club

Hello folks, I have started a brake master cylinder replacement on a '60 Traveller. I am following the Haynes manual but was wondering if I need to remove the clutch/brake pedal assembly or whether the job can be done without that? I'm struggling to get the clutch pedal off and thought the job looked 'do-able' without doing that? Any advice much appreciated.

To replace the brake master cylinder you do not need to remove the clutch/brake pedal assy.
Just disconnect the brake pedal from the master cylinder operating rod yoke. That involves disconnecting the return spring and removing the split pin from the double hole clevis pin.
This is the operating push rod which is attached to the brake pedal yoke.

If you are very careful you can remove the master cylinder whilst leaving the operating push rod and yoke connected to the brake pedal. You need to be careful with the rubber master cylinder front cover as it can be difficult to fit over the flange of the operating push rod.

Do not fit the bolts with the nuts towards the torsion bar.
The torsion bar flexes in operation and the bolts/nuts can rub against the torsion car and in severe cases cause the torsion bar to fail.
Use the correct thin headed bolts fitted the right way round - that is the heads of the correct bolts behind the torsion bar and the nuts on the inner face of the chassis leg.
The video did not show the problem encountered in removing correctly fitted master cylinder bolts. The torsion bar has to be deflected enough to allow the bolts to be removed over the top of the torsion bar (use search facility for details). The torsion bar does not have to be removed.
These are the correct bolts:-

As Phil says, you don't need to remove the pedal assembly, just extract the master cylinder itself.
I have a tool that makes this process childs play, link attached below.
Best wishes,
Mike.

Many thanks for all your responses your help is much appreciated.
So much for following the manual!

There is no need to completely remove the rear brake fitting. Loosen it enough to ensure that the fitting can rotate on the brake line. Then undo the banjo bolt from the master cylinder. It is much easier to start the banjo bolt than the brake fitting when re-installing. You do need to remove the side fitting, the line to the front.
