OK not 4x4 specific as such, but the other day I was working on the rear disc brakes on the Wife's Picasso, one was binding on the handbrake.
To be able to fit new pads you have to retract the piston, but not the old fashioned way of pressing it in with a G clamp and a block of wood, but you now have to press it in and also turning it either clockwise or anticlockwise,
depending on the manufacture/model type.
In the Haynes Manual it states both go clockwise.
Fortunately the brakes have some service life left and I am hoping that cleaning the pads and regreasing will sort it.
Is there a way of doing the retraction without forking out £35 - £70 to buy a tool and maybe use it once? :nenau
The tool has different heads that have pins that locate into the slots in the brake piston. (All new to Me).
I looked on Youtube and saw a guy trying to use a pair of long nosed pliers,
he slipped several times, which could have damaged the seals or cut his palm of his hand...
On another matter, I need to replace the front discs on the picasso as they have worn down to the minimum limit, what I don't understand, is there is plenty of life left in all 4 brake pads. Car has done 65 k miles though.
These are all original as we had the Picasso from new, I would expect the discs to last for 2 sets of pads.
I assume that the discs are of softer material, the car has ESP ( Electronic Stabilty Programme) so the discs and calipers are not Picasso standard, of course they are more expensive... Thicker and bigger diameter.
I have ordered some Mintex pads and discs so I'll see how these get on.
I won't need a retraction tool on these calipers and pistons.:nenau
Advice please,
best regards, Rustic.
