Rear calipers welding on

[Pistachio]

Since the salt has gone down, my rear calipers have been getting stuck on in the morning. So badly that I have to rock the car back and forward before they loudly snap free. I remember this happening on my old clio but not all the time. It happened today after sitting at work for 8 hours

I've been leaving the handbrake off whenever I can. Anything to worry about? Or just a 182 quirk?

They’ll be sticking, will need the piston and mech greasing and cleaning out. When was the last time you flushed the fluid out too?

I came to the conclusion it was not worth the time & effort, + the cost of a rebuild kit & went this way.

Will probably need 2 rear brake pipes @ £35 a piece too.

I just wound out the piston, cleaned it up with a very light scotchbrite, cleaned out the caliper, bled it all out (the fluid came out black!). Then I took off the boot for the handbrake, cleaned out the grease and then added some fresh stuff and used a set of grips to work the handbrake mech back and forward. After all that it was so much better! I cracked a disc when I first bought my dCi as the handbrake was that stuck on lol

It may work for some but can’t guarantee.

I've only had the car a few months so not sure when they were last done

I think I had aftermarket ones on my old 182 and the mechanism kept snapping if I remember right

Snapping is a singular event in my experience.

Mine do it all the time after heavy rain, it doesn't get driven that much either.

Just one of them things. Leave it in gear.

I think I went through three of them

I did drive through a flooded section of road recently so it could be because of that

More than likely mate.

Its just surface rust on the disc/pad from rain, my old Clio and current Octavia does it every time it pisses down then dries up. Nothing to worry about. Just make sure you release it gently as it can knacker the pads especially if track rated pads.

It could possibly be your handbrake cables need changing.

I refurbed my rears with this kit

There is a retaining clip inside the piston that is a pain to get out and back in. I used a socket that fitted inside the piston and knocked it in with a hammer.
