October 10th - Cylinder Head Removal and Insert Manufacture

On October the 3rd, the master brake cylinder failed, shortly after leaving home. I was literally yards from the house, so got back home ok. There were no signs of any brake fluid leaks from the master or wheel cylinders. As a result, I suspected the seals in the master cylinder. A new seal kit was ordered the same day, along with a front and rear cylinder seal kit, just in case they were the issue. The way the M201 Jeep had been parked in the middle of the garage, there was enough room to get around the GPW, although it was turned around in the garage to put the master cylinder on the side away from the wall, for better access.
 

 
The master cylinder was removed and stripped on the 10th. The inside of the master cylinder looked okay, with no signs of wear, pitting and no burrs could be felt. The new seals were fitted and it all went back together. Not having anyone around to assist with bleeding the brakes, the pedal was pushed down and held with a length of wood, jammed between the pedal and seat cushion.

The wheel cylinder bleed nipple opened and after a short flow of brake fluid, closed again. This was repeated until the air bubbles stopped on each wheel, pausing to top up the master cylinder with fluid every so often. A test drive up and down the drive seemed okay, but the weather hasn't been good enough for a proper drive yet.
