Brake Disc Puller

Spray pentrating fluid down between the stub axle and the bearing and keep working round it with a hammer don't just hit it in one piece.

Although tbh its needs a more constant force than shock loading to get it off really, can try getting it off with your hands either of the disc with a slight wobble to see if it'll start to come off. Otherwise a puller is probably going be neeed.

Usually happens when the bearings been running a bit hot, a smear of grease on the stub axle won't hurt when you reassemble.

This is relatively common - makes replacing the discs an expensive exercise though.

OP needs a proper hammer; a puny little claw hammer might be ok for hanging pictures, but isn't the right tool for this job. Get a proper big lump hammer and try to apply plenty of pressure to the disc with a pry bar or tyre lever at the same time as applying the lump hammer (ideally apply hammer to opposite edge of the disc from the lever - this helps to pull the hub squarely).

Is it?

I've have VW,audi, seat, pugeot, citroen, ford in the list of cars i've had and not a single one has a disc that is also part of the hub.

Is it me or is that the worst idea ever? As stated ^^ it must make things expensive to just change discs!
 
When I did my rear discs, there was absolutely no resistance to removing them at all.

I'm not sure if cutting it would be the answer, I'm guessing if it's stuck then the bearing is stuck on the shaft.

That's true, you'll just be removing the disc from the bearing and it's the bearing that is stuck. Might(?) be easier to pull on though.
 
Had the same problem with mine when replacing the bearing. I big hammer was all that was needed! Was a right pig to get off though!

How often do you change rear discs? Not very often at all. The Renault Clio, Megane, Laguna, Modus, Scenic and 19 all use this style of rear disc, as does the Citroen C3 and C4 and Peugeot 207 and 307

As has been mentioned, it really is supprising how much more effective a heavier hammer is. Get down to B&Q and buy a club hammer. It wont cost more than a fiver for the cheapest and it will get it off a lot easier than messing around with a puller.

Here you go, maybe a little more expensive, but think what you can smash with it :D

I could have driven to your house with my angle grinder and hammer, removed it, and driven home again by now :p

Get the biggest hammer you can find and put everything into it. I've had to do this to many cars. Transit vans are terrible to do, you have to smash them to bits before they come off usually!

Just had a thought though, I know the newer renault meganes.. on the rear brakes, the disk and wheel bearing are one unit, so you have you take the hub nut off to remove the disk.. yours isn't the same is it?

I've got to change discs this weekend on my transit. :cry:

Don't worry, most discs are just screw tapped on to the hub, nothing like the shocking build quality of french pap :p

I'd much rather all discs were on the hub like the rears on the Clio, then perhaps a drill wouldn't be part of the tool-kit you need to take to change a pair of discs.

You also have the upshot of discs with new bearings already pressed in.

And the needless expense of new bearings every time you change the discs. I reckon something around 3 sets of discs to each set of bearings needs changing for your average car. So that would be two times you'd be chucking away perfectly serviceable bearings :rolleyes:

Can I be your mechanic?! :p:D

I've never come across these disks that are part of the hub either, mind you I have only worked on a handful of French motors. I've always used a lump hammer to smash **** out of them!. It helps to hit the front part of the disc around where the wheel nuts pass through, this helps to break the bond between the disc & the hub. Applying a tiny bit of copper grease to the hub helps to save grief the next time around!

I never bother with the screws on front discs to be honest. The wheel holds the disc on anyway, the screws only rust in/round off.
 
I presume you have tapped it all the way round into the middle rather than smacking back to release it? I see people wack the ***** out of them and not come careful few taps normally dislodges them. Tap towards middle of disk and turn then bash from back

And as I already said, how many times do rear discs get changed on small hatchbacks? Perhaps once, maybe twice in the cars life?
 
I agree, but Mike said he wished all discs were like that!!!

Yep, once I used my impact driver to get the screw out I never used to bother replacing it either.
