Need some help i have 2 pot calipers fited to my subaru and the pads are over hanging the disc,s and pads have now got a lip on , also looking for 4 pot caliper brake disc dust shields for the front as mine have rusted away , on top of that i have a siezed piston on my front 4 pot caliper and cant get piston out i have tried to push it out with brake pressure but wont move at all its solid, any help with these isue i have looked up the rear disc and it is the correct 1 , just had to replace rear calipers on both sides as pads where solid and calipers were beyond repair as to badly coroided so that was an expense i could have done without.https://cimg1.ibsrv.net/gimg/www.sco...7e230a9e3f.jpgNew rear caliper fited with new pads .

Lose the dust shields, they aren't necessary.

I wouldn't worry about the rear pads, it won't cause any harm, will just be manufacturing tolerances. Those rear calipers aren't too bad. The external corrosion is nothing to worry about, just clean them up with a wire brush and then paint. Probably could have rebuilt them for £70 with new stainless steel pistons and seals.

To remove the pistons from the front calipers, soak them in WD40 and then try and turn them with mole-grips. If you are going to replace them with new stainless steel pistons, you can get medieval on them. Compressed air works too; either a compressor or an electric tyre pump.Use and old brake line and cut the end off.

I'd be replacing all the other fluids too if the brakes are anything to go by!

Thanks for info, will try that on front caliper once i have been to show with car, i have replaced all other fluids ,just brakes to sort out i have flushed over 1ltr of brake fluid out so far but going to wait till i sort out sized caliper first :-) nice to get advice thanks again

Were are you in Wales?
I am just putting a set of 4 pots back together having refurbed them with stainless pistons.

Down in west wales,

Bugger. I am near Newport.

I ended up buying new calipers as it took me ages to free the pistons up, by the time i acid dipped them and cleaned them up. I had already bought new aftermarket calipers and fitted them after a good paint.

they looking very nice great job, you can do mine 4 me lol:thumb:

Your discs are facing the wrong direction.

Disc
 

Who disc are the wrong way ? Hope they not mine as garage put disc on lol

Yours are. Sorry.

What matters is that any internal vanes if they are slanted, do lean away from the rolling direction.

I thought the comments about US Porsche Engineers rather funny.

and for every argument (google link) there is a counter argument

best thing i find is just to ask whoever makes your discs :p

No counter argument involved here , I don't believe the vanes inside are slanted on the disks shown by Jaygsi Scotty is right @11:28 they are on wrong.

I'm only trying to point out that you need to know about the vane direction before looking for hole direction. In my own view if slots are employed for gas expulsion these best positioned in laid back to rotation direction as this helps accumulating dust to be thrown out centrifugally by the rotation force.

^^^^^^

A few of us had this argument stood next to an AM Vantage one day. The grooves were not the same on each side, having spoken to the engineer he explained the internal vanes did not have a directional bias to draw air in.

Off we went with a skip in our step.

Think he's referring to my discs. :eek:

Is it going to make much difference? Thought there mainly to vent the heat.

Brake bleeding sequence is:

Front Right
Rear Left
Front Left
Rear Right

You need to bleed them twice. Do it once and then drive and get the ABS to engage a few times. Then re-bleed and brakes should be good.

But external vanes?

External grooves not vanes matter not depending on the inner pattern.
