Master Cylinder Repairs
Posted: Tue Jan 29, 2019 4:53 am
Hi
I have begun working on my Haffy again. Started to work on the brakes, have replaced the break pads and cylinders in the wheels. Upon starting to bleed the breaks I was pumping the break pedal and a pin/something seems to have disconnected from the back, so that the pedal will jam on depression and can be corrected by lifting something at the back underneath the steering box.
To understand the issue I need to remove the master cylinder and check out the problem. It looks like a difficult job because of the poor access to the links sitting at the back/under the steering box. Might as well service the master cylinder whilst it is out.
My question is will I have to remove the steering column to be able to connect/reconnect the master cylinder to the break pedal??
Is there any guide on how to remove and service the master cylinder?
UPDATE I removed the master cylinder and the inner workings have siezed with corrosion on the inner surface of the barrel. I suspect I will need to buy a new one.
One more question. Where the break line attaches to the exit of the master cylinder, the nut on the break line itself is brass?, is there a trick to getting these loosened without burring the edges of the nut?
Thanks
Craig
