Master Cylinder Reservoir

When I fitted the uprated master cylinder and servo some time ago to the DHC, which is sourced from a Rover SDI, it had a rectangular reservoir which sits level when fitted on the SDI, but is inclined when fitted on the TR7 bulkhead, thus all the fluid is at the cap end and it is virtually empty at the other end. I did not have a serviceable reservoir from a TR7 at the time so stuck with the one supplied.

I found a correct TR7 reservoir recently for next to nothing on fleabay, so today gave it a good clean up.

I then removed the SDI reservoir and fitted the TR7 one, this I managed without getting fluid everywhere, I simply removed the 2 screws, then with a shallow container under the cylinder and an old quilt cover to soak up any fluid, quickly pulled of the reservoir allowing fluid to run into the container, handy these plastic Chinese Takeaway containers.

I was not worried about getting fluid on the paintwork in the engine bay as I use silicon fluid, after bleeding the brakes I ran out of fluid to top the reservoir fully, unfortunately living in a small country town none of the local garages stock silicon fluid, however there was enough fluid for a quick spin around the lanes in lovely Autumn sun. As usual my planned 5 miles turned into 15 as I got carried away!


  1. HI,

    I'm Searching the same reservoir as you find. May you give me the reference or where you find it ?

  2. Try Robsport who may have a second hand one.
