Clutch master cylinder refurb

As suspected when I bought car and found that the clutch fluid reservoir was empty there was a leak from the master cylinder. Removing the clutch reservoir was quite straight forward – the brake light switch needs to be removed to gain access to the lower fixing bolt. I placed a lot of rags under and around the cylinder and on the carpet in the footwell under the clutch pedal.

The cylinder was dismantled very carefully making note of the position alignment of the components. A pair of long bullnose pliers is ideal to remove the main circlip. When dismantling the piston assembly I strongly advise wrapping it in a cloth when the spring is released to prevent it flying apart. I found the instructions provided for the TR6 – which shares the same unit – very useful. The bore was clean with no scores or wear rings so good to reuse.

When reassembling the piston assembly best to have the piston wrapped in a rag in case it springs apart before the locking pin engages.

IMPORTANT …… The final part of the process is to bleed the clutch hydraulics so make sure you have the car on ramps to gain access to the slave cylinder bleed nipple prior to starting the job.
