Brake advice

Postby bishen67 » Thu 26th Mar 2020, 03:43pm

I have converted my 84 drum braked Mayfair to discs.The car is Sorn so cannot road test apart from a couple of foot on my drive. I have changed to shorter fiexis but kept the drum brake master cylinder. The pedal is so so but there does not seem to be a great deal to stopping power. I know that the pads need bedding in, do I need a different master cylinder?

servo or non servo?

non servo needs a firm pedal.

also, if you havent bedded the disks and pads, they wont bite properly for a while

is the pedal firm?

Aren't different cylinder supposed to be fitted to the rear in order to make the caliper bite?

Take a look on Minispares at the different descriptions of all the different rear cylinders, the notes are quite handy.

I have messaged Minispares directly asking the same question, and the answer was that when most people convert to discs, they do not change the cylinders, but they gave me a part number in case I want to. As mine are new cylinders, I will keep them and just bed the pads in properly.

Ok thanks, may be some time before I can road test it. I will have to put it on stands and run it up to her the brakes in, that is when I sort the carb out. :D

Ref. Brakes, as I cannot road test it, I ran the car up while on stands, and with it in gear, herded the front pads in, pedal seems better now. I will run the eezibleed once more and readjust the rears: A future road test will confirm if they stop the car. Thanks for your advice , and everyone else’s.
