Gradually de-bodging my tools over time... Looks pretty universal and would apply a good amount of leverage by the looks?

It's fine, not amazing but doesn't have to be. Mine has an enormous amount of play now but then it's about 15 years old. The wee lever bar isn't up to much and gets in the way a lot so I cut it off and just use the tool with a ratchet in the end instead.

I got one of these this year, I'm still not sure if it's actually better or not but it's incredibly pleasing.

What's wrong with a screw driver and an old pad?

robj20, nothing wrong with the screw driver method, it's just a job that irks me with my Guides as it feels like the bodge which of course it is.lol Plus I just enjoy having the right you for the job tbh.

Northwind, the one you link to is huge? Do you mean it's nice to use on motorbikes or such?

Cheers matey!

Well I think like me he is thinking .....surely this isn't for a mountain bike as you'll never get 2 of anything meaningful between a set of pads. And I wouldn't push directly onto pistons .

Eh? Why not? The pistons push on steel backing pads. OP's tool looks pretty god.

Er, good.

As mentioned above, that item is for automotive brakes and won't fit at all.

If you want to buy something get the Park Tools PP1.2 or one of the similar ones. Don't push directly on the pistons - use it between the pads or some old ones (so you don't damage the pistons and also gives improved leverage).

Well, cars- yours is a car one too so I assumed that's what you're looking for. But if you're looking for a bike tool then neither is any use at all, just too big.

(for scale, the hex on the end, beside the lever, is 21mm IIRC and contains a 1/2 inch drive. The metal plates are like 2 inches by 5 inches or something)

For whatever it's worth, for bike pads I use some old pads and my Really Big Screwdriver. You know the one, you've never used it on a screw but it's awesome for opening pots of paint? Perfect. I have an official "mountain bike pad spreader", it might even be a Park one, but it's not as good.

^^ I'm a bloody idiot.

Basically I need the meme of father Ted illustrating "small... far away... small... far away." Lol

No idea why but assumed it was bike sized!

Could swear I saw something for mtb sized ones online but might be imagining it?

If so, screwdriver and old pad it will continue to be.👍

You'll only brake one centre knob off avid or Hayes pistons and you'll change your kind or point load a phenolic and split it across its self .....and you'll change your mind.

It happens more often than you think.
