I have a set of the XU-1 spec caliper spacers from Perth Brake Parts, planning on fitting the caliper spacers between the two halfs myself so i can run the thicker discs. any one have any tips? which way do the machined bits of the spacers face? and do they require some sort of o ring? haven't split the calipers yet so sorry if the anwers is obviouse.

cheers

Hi red 6 if you buy the caliper kits to suit XU1 which is a good idea (only about $23 per side) as whilst they are out you may as well replace the large o rings on the pistons and the dust boots the correct o rings come with the kit to suit the spacers it looks like a flat o ring.
Hope this helps Dave. Buy the way Repco do the kits as well.

question, do these kits include bolts?
the XU1 bolts are longer to allow for the spacers

1. Never seen a caliper spacer for sale at Repco (I assume you just mean the rubber kits)
2. Yes they are a flat seal but you can use an Oring on the spacer
3. No they don't need longer bolts... its only 3mm... but fit them if your paranoid... off to the nut and bolt shop with you
4. When you get the calipers apart you will know where the machined section (with Oring) goes
5. If they didn't sell you Orings to suit with the calipers I can see they still employ numpties
6. You may need thin spacers between the stub and caliper to centralise the caliper on the disc again ... orig cars had these... no PBP aren't smart enough to make them and supply them with the others as an actual usable kit... refer numpty remark above.

Yes dattoman you assumed right Repco just do the rubber kits which unfortunatley after ordering all XU1 brake parts from PBP you would think that they would have given me the right kits for the XU1 calipers. So I went to my local Repco and they had the right kits on the shelf.

Neil,
when are you going to have someone doing proper kits?
I'm sure someone would wholesale you a rubber kit to include............

Speak with sstorana........I'm sure it's something that would fit well into the product range!

Grant..

I thought Mick only did parts for Toranas... not Vauxhaul Vivas

I can get the plates and spacers made
Just need to find my samples somewhere in the shed

FT is the norm

[S pack]

A tee bar and four foot of water pipe or not quite that tight>>>>

70 ft/lb

[dattoman]

Not a secret now is it ?

I would find it unlikely anyone would use a torque wrench to assemble a caliper... any caliper

70ft/lb is not a figure derived from any manuals etc.
Two pairs of XU1 calipers that I dismantled to replace the seals both registered between 60-70ft/lb to crack the bolts.
So when put back together I torqued the bolts to 70ft/lb. Some might say that is not an accurate way to find out the torque specs for a bolt, but without any recorded specs to work with back engineering was the only other alternative.

split the calipers and discovered that the spacers PBP sent me were an incoplete set. the two milled spacers were milled on the same side so both suited the LHS caliper, been waiting 10 days so far for the replacment set to turn up. Been waiting 4 weeks now for the DBA slotted rotors to turn up too.

Lucky the car isn't registered at the moment.

Just checked the spacers i bought from them mine are right. I got DBA slotted rotors over night last week.

[red6]

DBA rotors took just over 4 weeks to turn up, had some problems with the slotting machine so they had a back log of work apparently.

been waiting since before easter for the correct set of caliper spacers to turn up. so 4 weeks and counting. Apparently they sent one set but i never saw anything and the second is yet to show either. getting pretty impatient. to make it more frustrating i ordered the first (incorrect) set over a year before i actually went to use them because i had heard they were unreliable.

[red6]

finally turned up after 2 sets lost in the post and 6 weeks of waiting...

[dattoman]

I think it was more likely a supplier issue than a post issue...... idiots

[dattoman]

Thats the rubber kit yes
Can also use a K785S but the channel seal is wrong
I usually use the 785 and use 9x2 mm Orings I buy from Bearing Services
But thats just me
If using spaced calipers... you need to get some extra chanel seals anyway cause theres never enough in the kit
Oh and the pistons are a DB2278 if you find you need to replace them too

Nothing to do with the spacers though
They are long gone and being laser cut by some people only

Gong was going to do these but I guess decided against them

If there is interest I'll get them made
And if someone has a sample stub spacer that goes between stub and caliper and sends me that I'll have them made too

[dattoman]

Pins are gone
So its splitpins or make your own
6mm stainless I think ... but my memory is going
