MG TD brakes

[Robert Leigh]

There is always the possibility of underuse with hydraulic brakes, particularly with old fluid which is hygroscopic. If the fluid has taken up any water it can cause rusting in the cylinders; if these don't work freely the brakes will be poor. I suggest some donkey work checking whether all the pistons are operating freely and the return springs are in good order. Modern synthetic fluid is not hygroscopic, but it should not be mixed with old fluid. If you are going to change over the system should be thoroughly flushed out. In my view the biggest enemy of hydraulic brakes is lack of use, which often occurs with 'collectors' cars.
