Would you just pop the seal back in and install it again. It could be it was too cold or not properly inserted

Or would you buy new seals?

It had tones of grease at back of the piston
Is this how they rebuild?

I bought the front and rear kits from alpha omega racing over a year ago so things may have changed but a few things spring to mind:

1. During the order process for the kit, I had to specify the car model that the kit was going into. Presumably this dictates the components that make up the kit.

2. Depending on what kit you bought, (or separate components?) you may need to rebuild the calipers prior to use. But maybe you bought the rebuilt calipers?

I bought rebuild calipers from someone in the uk

Would you just pull all seals out , apply fluid and have another go or change all seals?

They are all brand new but not sure what brand the seller has used

He also had applied significant amount of grease (red) to back of the piston which reading around some people do it and it is apparently compatible with break fluid but i don't like it as that will get mixed in the fluid

Refit the dodgy seal and try again.

will do in the morning. 6 hours to sleep and start over again

another issue was the bolts supplied by alpha omega were screwing in quite tight in one caliper only 

i did re seat it few times to ensure it is not going in at angle but still was tight. so having worked 11 hours, I was pretty annoyed and did screw it in all the way.

they did torque up and did not damage internal thread but apart from one area of the bolt which has part of the caliper threar on it i think

they do both torque up with no issues, would you re thread?

Internet diagnosis of thread health is very difficult.

If fluid is getting past the seal then either the bore is damaged, the piston is damaged or the seal was damaged during installation.

Here's a crazy idea, contact whoever you bought the calipers from and tell them they leaking. What's the point in buying "rebuilt" calipers when you have to rebuild them yourself?

[stranger12]

I have already but need the car back on road and nothing is going to happen in these few days before new year

I think he has used general seal kit and not brembo

I think the issue was he had not put the seals in correctly so will give it a go

[stranger12]

It was a damages seal and seller said it might have been damaged when he has pushed it in

Would you shell out£200 for set of brembo seals or get them off ebay?

He swears by brake international and it is way cheaper£60

[KiwiRS4T]

For 200stg I would want a complete set of Brembos! I would try the 60 ones and spew at paying that much.

[Sick_R31]

If the seller damaged the seals during installation, he should have to pay for it, simple.

Pommy ignorance but look at the tenacity, winner.

Get rid of the grease, filling a caliper with it is utter bullshit. Bolt threads can get damaged for no apparent reason, if a bolt is a bit tight then run a tap through the thread to clean it up. Cheap set of China M taps is fine for this. Rum&Coke will fix any other worries.
