V40 Rear brake pads change.

pd1146 · Oct 26th, 2010, 15:21

I normally use a large pair of waterpump pliers to press the pistons back into the caliper when changing brake pads.
But this isn`t working on the rear brakes of my 1999 V40, and the Haynes manual says I need a special tool to wind back the piston.
Any help on this would be greatly apreciated.
Many thanks,

Yeah, they need to be turned as they are pushed back in. Think you can get the tool from any car shop for less than £10. I used a g clamp on mine, worked and had no problems so far.

Hi,

Hey up,

Yup, you need a caliper winding tool.

Laser do one, most motorfactors will hold them.

Halfords will probably stock one too.

A worthwhile thing to have around for future changes.

I'm told it's really really really not a good idea to force them back.

Something to do with ABS?

My rear calipers wound back a long way, so trust the tool and it will keep going.

Cheers,

Daniel.

the g clamp does turn them as it pushes back in

Buy a proper tool and, to avoid the risk of reversing master cylinder or ABS seals, open the bleed nipple as you're winding the piston back.
Don't forget to check and grease the caliper sliders - one or both are nearly always seized and lead to uneven pad wear. In fact with the proper tools and techniques the rear brakes are a doddle.

Hey up,

I used a G-Clamp on my front calipers.

Unless you have a magic wand that keeps the caliper very very solidly stuck to the caliper piston, the g-clamp will spin on the piston, not turning it as it pushes it back. Super glue doesn't work.

There is no substitute for the proper tools.

Cheers,

Daniel.

I made a simple tool utilising an old 1" AF socket and an angle grinder; grind two flats about 4mm deep on the business end of the socket, leaving two prongs sticking out to engage with the piston indents. It is important to wind the pistons back!!

I have the correct tool if you want to borrow it.
