Really? A professional workshop installed them? I would be mocking them the next time you speak with them that you prefer they dont drink when they work on your car

Its not a big deal at all. Rather simple. Its right up there with people who piece together kits and install curved vane rotors on the wrong side of the car not realising how the curved vanes work. Its no biggie...but on a track car will work properly if installed properly.

The point of the bleed nipples is a simple fix...but an important one for the person who takes them off your hands. The Advantage Mono6 caliper which is what you have has different sized pistons in the caliper. They are different sizes to keep uniform pressure on the pad and rotor face. The leading pistons should be the smaller; the trailing the larger pistons.

You are all correct in the bleed nipples need to face upwards...but look at this pic.

That pic is passenger side ...now think about which way the rotor passes through the caliper when driving

The pistons near where the A of Alcon is the smaller (30.2mm) piston and the other end near the logo is the 38.1mm piston. The way they have installed your caliper is that the large piston is the leading piston and the smaller piston is the trailing. That is wrong and will give you rather poor pad temps and wear....essentially hamstringing the performance of the kit from what it will be capable of.

The fix is when they are off the car then you remove the bleed nipples, remove the external fluid line at the other end of the caliper and swap them over , effective flipping the caliper so the piston sizes are correctly orientated. Of course this will mean what is currently the drivers side caliper will become the passenger side caliper and vice versa.

I have the big brother Prodrive version of this caliper on a 380x35 R35 rotor...they are a good piece of kit and whoever buys them will be stoked....its just that they arent configured right for a Nissan

Link is wrong.

Now u understand the problem.

Easy fix though.

[sycorb]

so the caliper is upside down

and the nipple goes where the smaller pistons are is that correct?

sad to say Roy but i think that you have used the bloke that installed these rotors as well

so are the rotors right that pic is passenger side?

not many people are fans of his anymore

Brad from profab

brad what a kunt

[portaz]

Ok makes sense thanks for that I'm sure it's a pretty common mistake

[sycorb]

i heard he is working somewhere in penrith

he's getting closer to you fatz you wont have to travel as far to see him now lol
