GTI Caliper Issue - Seized 'Slider/Damper' ??? - ginge191 - 15-04-2012

Pics describe this better than words..

Basically, taking the carriers apart, on each carrier there is 2 damper type springs on each side...
on each carrier i have one seized

The boot to protect it from seizing has obviously failed at some point and rusted the inners - the insides are greased which acts as the damping for these little widgets.

Anyway, anywhere i can new ones from? Besides the scrapyard as we have NO Gti's in our scrappies, OR is there i way to get these out - got some WD40 soaking at the moment and a lot of MTFU on it..

Heres some pics.

GOOD! Big Grin

EDIT: ALSO saw Johnny re-build his calipers last year, read it on .net, maybe he could have some input if he's around, rather than his usual spam..

Also if they don't need a new seal set then don't it's a fecker getting to pistons back in with new seal as well as getting the rubber in its recess

Ok, update, Dan, it's cool mate, i'll see how much the new bolts cost... will keep you in the loop Smile

So, i managed to get both out, the 2nd was an absoloute PITA - ended up BENDING the bolt, mental - got a drill and wire brush adapter and blitz'd them for couple of hours, hands are killing but they look clean and fresh now, gave them a lick of black hammerite and they should be fine.

As for the main piston, would you be able to test them with your hands? i can compress them and it squirts everywhere, good enough?

Anton, i found them on ebay and sent them a message for the specific part, i'm not sure what im looking for/size/spec etc.

Ginge bring them along to Ace tomorrow and ill have a look, I fear that even though you have "smoothed" it back, that the hole will be slightly bigger than the sliding pin

GTI Caliper Issue - Seized 'Slider/Damper' ??? - Jonny b - 15-04-2012

Will bring you some proper caliper grease as well on Monday,, Iam sure they can be saved

Re: GTI Caliper Issue - Seized 'Slider/Damper' ??? - ginge191 - 15-04-2012

Yeh, i'll bring them tomroow..

Where can i find the code for the caliper - i've found the slider pins, but unsure on caiper code - can't find it on the caliper?

measured the pin and its 70mm in length, 10mm width, but they offer 5 different pins...

Ok, for those of you that maybe interested - been in contact with BiggRed http://www.biggred.co.uk/, and posted my bolt to them

He (Tony) has found the correct bolt, an Astra bolt http://www.ebay.co.uk/itm/270955072452?ru=http%3A%2F%2Fwww.ebay.co.uk%3A80%2Fsch%2Fi.html%3F_from%3DR40%26_trksid%3Dp5039.m570.l1313%26_nkw%3D270955072452%26_sacat%3DSee-All-Categories%26_fvi%3D1&_rdc=1 which fits and is the same measurements.

Just paying for 4 new ones, great help indeed - be aware, the bolts do not include rubber seals/boots so will need to pay for them seperately
