Hi guys!!!
My mini has sat for awhile now, and my break pedal is awfully stiff. It takes alot of force to move it 2 inches. Anybody have any ideas what is wrong with this? Thanks!!

It sounds like it could be partial seizure in the master cylinder.

Yeah mine was like that for the first couple of months I was driving it but it loosened up....if you bleed the system through it might help loosen it.

It is a 85 mayfair. It doesnt have a servo so perhaps it is the master cylinder. I will bleed the system this weekend also! Thanks guys!!

If there is air in the system the pedal would feel spongey so i doubt its that

What tends to happen is on any car left standing, as the metal parts of the braking components, take the disks for example are exposed to the to moisture in the air surrounding them, they rust over very quickly. now this isn't really a problem for a car that’s used every day as the build up that forms when left is normally worn off after a few applications of the brakes.
But for a car that has been left for quite a while will have quite a build up of rust on the braking components, and in much the same way you have to bed in new disks and pads, the braking components will not be making full contact with each other and reduce braking performance, causing the pedal to be a little stiffer than normal, and will so need a little more effort to stop till all the rust has been worn off.
I wouldn’t worry about it too much as it should fee up after use.

its a non servo cylinder!! the handbrake is probably on!! getting 2" of movement is going to be a miracle!! you shudnt get much in a well setup system anyway!!i usually found most of the pedal travel is in the rear cylinders
if the handbrake has been on a long time the rear cylinders or shoes mite have siezed!! does the mini move at all??
