Alpha omega racing rear brake

[drifter17a]

All

 

bought the alpha omega bracket kit for r34 rear as had it in front and it is good

 

for those who don't know, it is 350z rear disc with brembo is evo 6 caliper and bracket of course

 

now after mounting it which comes with a drive shaft spacer, it seems too tight between the lower of the caliper and disc

 

is that expected if anyone has installed it?

 

disc rotates but think it will rob

Take it all apart, put it back together again, in case you've managed to misalign something on the 1st time 'round. Shit's supposed to be parallel.

[Duncan]

That is not right somehow, and shimming it won't fix it.

[drifter17a]

I followed all instructions and puzzled

 

it has a hub spacer which I installed and drive shaft ring thing which 
 

does toe or camber angle change position of caliper to disc?

[robbo_rb180]

Get a set of vernier and a square measure the adaptor bracket and the caliper for thickness evenness and square. 

Wonder if caliper was from a crashed car and is twisted? 

[Robzilla32]

It looks like the caliper is displaced due to the piece of webbing fouling but I thought that was the purpose of the hub spacers.

Waiting on alpha omega response

 

spacers goes in one way only so i could not havr mis aligned anything as all holes must be aligned for it to go in

calliper is good so only thing is the bracket is screwed?
 

could camber or toe impact position of disc i. Relation to caliper? I wouldn’t thing so as knockle is not flexible so toe pr camber won’t pull bottom side down or vice versa

@_Wing_  seen this issue?

Can't tell shit from those photos aso what is happening except it is wrong. The last photo is sort of handy, take another one like that  of the other bolts

Seen it a number of times; the upright is bent

 

Thanks! @robbo_rb180

[drifter17a]

So all sorted 

 

Issue was the disc was not bolted down with wheel nuts and brake dust metal was catching it not letting it sit fully

 

All sorted and panic over

 

I noticed the right drive shaft nut sits slightly further out then left so pin won’t go in as two layer/ double sided

 

We had to open it and lock it as attached 

 

Does this look ok?

[Ben C34]

I've lost all faith in your mechanical abilities. I'm out

[drifter17a]

No worries 👍

And now huge screaming noise from both rear after say 30 miles

 

pads are both brembo and disc is new

 

cleaned it with brake cleaner but it is so loud on braking that people from few hubdard yards away turn around

 

i didn't grease back of the pads and just stuck them in. Any thoughts?

 

when bought caliper it had two metal peices going on back of the pads which I lost. They are the anti vibration plates and think that is causing a massive noise

 

as I understand the squeeking comes from brake dust and contact surface but clearly i am wrong
