Windback Tool

[Innocent]

I'm fitting new pads tomorrow but dont have the windback tool. Any ideas where i can get one from? Halfords?

Yep - Halfrauds should have them, about £15 I think

There's a picture of what it looks like HERE   s:wink: :wink: s:wink:

and how prescisely did you wind it in with a g-clamp  s:roll: :roll: s:roll:

on most cars the piston will push back without too much of a problem. The G clamp will work as will a screwdriver between the brake pad and disk. By all means spend 15 quid but I doubt that you'll find mr T's technicians using a special tool.

And after you have knackered the threads in the caliper by using a G clamp £15 will seem very cheap indeed   s:wink: :wink: s:wink:

I'm quite prepared to learn here.
So does Toyota use different calipers to most other manufacturers?

Fronts just push in (using a G-clamp). I know - I spent this morning changing my front pads and disks (less then 1mm of pad left on them   s:oops: :oops: s:oops:  )

Rears need the wind back tool due to the auto-adjuster for the handbrake.

No, because Vauxhall and many others are the same.

The rear calipers (only, not front) screw back in - inside the caliper they are threaded, and it's this thread which is the self adjuster for the handbrake.

You can't just push them straight back in - if you can, it's broken.

[edit] Which Steve already said  s;) s;)

Here's a question that needs to be thought about, if the caliper is threaded why does the wind-back tool need to be locked on the opposite side of the caliper and have a threaded stem to push the piston back - are the threads on the wind-back tool the same as the inside the caliper  s:?: :?: s:?:  

I did use the tool to rotate the piston to line up with the peg on the pads, in fact I rotated through 360 deg and it did not appear to go inwards, indicating that the piston was either not threaded or the thread was very fine - which would be in conflict with the wind-back thread which is course.   s:? :? s:?  

Any way I did use the tool for both rear calipers - it worked but not exactly as I thought it would  s:? :? s:?

Oh yes I forgot, if the piston is locked against the pad (peg on the pad) when you apply the brakes it will not rotate - so the piston is pushed out and does not rotate - so what's going on here then, is the rotating when you replace the pads something to do with the seals as you push back? It's like a chicken and egg question this one  s:oops: :oops: s:oops:

Replaced the pads yesterday and yes, as already mentioned, the windback tool is 100% necessary. As aaron said, you could possibly get the piston back in with a g-clamp if you're feeling strong but the high risk of screwing up the thread on the handbrake ratchet isn't worth the £20 for the tool! Was hard enough work to wind the piston back in with the tool with one hand holding up the caliper.
