Brake pedal sticking

[pugsport]

My 406 has been standing for a couple of months, the brake pedal stays down when depressed. I have to hook it up with my feet, the brakes then release. before I take bits off and check the pistons for corrosion, what else should i check?
how does the pedal normaly return, is it spring loaded or does the brake servo do something?

I had sticky brake pedal and it was a sticking piston in the rear brakes.

I start checking the brakes to see if any are sticking, i d start at the back if you have rear discs.

Old thread, but it seems to be the only one for "brake pedal sticking" so I thought I'd add to it rather than create a new one.

Actually, about the time this thread was created my 406 was going through a phase when the brake pedal would always stick down and I had to kick it back up to release the brakes. It cleared itself up after a few months.

However, it always sticks if I brake very hard.

Anyway, I can feel that the brake pedal is getting a bit lazy to come back up.

I'm sure I'm well overdue for a change of brake fluid (any tips?), but what could be causing the sticking?

Before my time this thread Reading it I'm having doubts that I know how brakes work bcause I'd have thought if a rear caliper piston was stuck the pedal would still come up because the pistons in the master cylinder act like a valve, on the way up there's nothing to stop the fluid going past the seals and this is the way more fluid goes into the system as the pads wear.

Before that I would have said obviously a master cylinder fault but now I don't know

i had a sticking brake peddle once all but one of the calipers where seized and let by in the master cylinder the rear brake calipers had pistons and sliders and the front had a part seized slider pin fixing the seized parts fixed the sticking peddle
