[Brakes] Berlingo M59 sticking front left caliper – SOLVED –

[brajomobil]

I had the issue last week so I would like to share the experience and maybe help someone.

I have noticed on my steering wheel that car tends to go left.
First thought was that tire is not properly inflated.
When I wanted to check tire pressure I have notice that wheel is hot.

I have removed the wheel and opened the bled nipple.
Oil came out but the disc is not yet spinning.
So I thought, good it is not the break servo and no brake hose either,
it must be the piston or the sliders.
As I removed the lower caliper bolt disc was spinning freely and I saw that sliders are OK.
Then, something must be wrong with piston not returning to its position.
Took a closer look and noticed that protective rubber seal around piston is not tight
and dirt has come inside creating some sort of very sticky compound around the edge of the piston.
Pumped the pedal a few times (be careful not to push the brake pedal all the way to the floor,
put some brick on the floor of the car) so that around 3cm of piston came out.
Cleaned it with wd40 and clean cloth, and returned it back by hand.
Then pumped out again and cleaned again, 5 times I a row.
Each time piston was sliding back easier.
Reassembled everything together and no more hoot wheels
It took me about 45min to get the whole job done.

There's been quite a few reports about Berlingos pulling to one side or the other.
Could this be the cause for some of those?

Maybe people should start checking the temp of the brake disks whenever this happens?

Incidentally, here in Norway, the guys from the DMV that's out on the road, pestering truckers have a fancy toy...
A pair of IR cameras they set up along the road. That allows them to see the temperature of all the wheels of passing trucker. Now they only have to wave aside those with abnormal temperatures for testing.

Good find well worth a look with other berlingo's pulling to the left just wondering if the mk3 brake calliper is the same type as the mk2 i think there are two types on the mk3 on some mk3 the tyre seam's to be the problem cratch:

I have just looked at Citroen Service Documentation and TecDoc2013
unfortunately mk2 caliper and piston is NOT the same as mk3
