TR4/4A Rear wheel brake cylinder replacement


Jedi Warrior

I have a leaky rear wheel brake cylinder. It's been a while since I've wrenched on my TR4. How big of a task is it to replace these? Are there any videos available?

Been a while since I had to rebuild these on my 3A. Getting the WCs out themselves can be quite fiddly because of the two piece metal bits that interlock and hold them to the backing plate. Easy enough just to clean and replace the seals and lube them; cleaning out the old brake fluid, etc. It’s been covered here in the past.

And then bleeding them, always fun!
