I guess I'll keep on driving and see how things are after a fortnight. Maybe rebleed again >_<

I suggest the MC is the right size. It's bloody huge :blink:

My suggestion is to bed the brakes in.

Somewhere on here is a procedure, but basically go to 80km/h and stop hard to 60, repeat around 6 times bordering on ABS engagement. Then 100 down to 40 twice bordering on ABS engagement, then cool slowly (drive around 60km/h with the occasional light brake pedal to slow and then speed up)

Don't ever physically stop... otherwise you'll warp disks etc.

I'm sure there are other brake pad bedding procedures etc, and my memory may be failing me.

After you have done this, it should be good to go and your pedal travel may decrease

Where the rotors machined before you got them or did you sand paper them before fitting?

Where the pads new?

I seem to remember Danny being a little underwhelmed with his setup until it was properly bedded in; similar to you, he was saying they were soggy to begin, but as they bedded in they were heaps better.

New rotors and pads...didn't sand it but I think Scott sprayed them with something to get rid of the anti corosion film.

I did about 2-300km's of driving after the new brakes were put on. So I guess maybe I should do more "bedding" in driving...

Are these things worth it? Awfully expensive for what it is!

I am pretty sure Chris(Akebono) and Ben(Brembo) have not replaced there master cylinder or brake booster either.

Yep, Ben changed to the 350Z Brembo and I changed to the 370Z Akebono (just a strait bolt on - no other changes made). I have about 1 inch of pedal movement. No pumping... just shit loads of power. Ben's is very similar to mine. We had to bleed them 2 times till we were happy.

Driving around the street and bedding the rotors in are two completely different things. One you are just scraping the surface, and the other you are actually embedding brake pad material into the rotor which provides the stopping power you require and also 'moulds' the pad to the rotor (to some extent).

Bed and bleed. Job done.

they dont fit on our car.. 350z bay is VERY different.

:stupid:

I did read an Engrish blog yesterday where a modded NM35 running the Brembo's on 355 discs upgraded to a BNR34 master cylinder.

He said that it was a perfect fit and a definite improvement.

He also said that the Z33 would not fit and was a little upset at the wasted money lol

You buy it and tell me it fits. just like the engine cover with a spacer :nyaanyaa:

Sensitive? Would you prefer I simply put a "+1" if I agree with you :P

I was just offering a little information I picked up regarding a possible brake master cylinder upgrade.

At the risk of going waaay off topic with you, I have installed a few spacer kits where the owner wanted to keep the engine cover on... and they do fit without modifying/cutting. I'll have a look at yours next time I see you if you want.

Hmm screw the engine cover I'd rather fit a strut brace....

possible with the spacer?

OK, so the consensus is taht cylinder upgrade not needed.

Will try to bed them in tonight. Maybe rebleed again...u gonna luv this scott...

re bleed them after they've been bed in. i reckon anyway..

and cam you have my seals anyway so i should be seeing you soon. if you can make it fit with the bonnet closing? I'll be happy

I did say my memory was failing me!! :nyaanyaa:

Their test sounds more aggressive. Really if you don't get the 'green fade', then it wont do anything.

no, no you cant. Theres about 3mm gap without the spacer.

What is the capacity of our braking systems? Trying to work out how much fluid I need...

Also, opening a can of worms, how do you know what temp brake fluid you need?

Searching tells me everyone uses a variety, or doesnt talk about it, with Motul RBF600 the most popular. But when I was at Autobarn today, it was 3-4 times the price of the Performance DOT 4 alternatives from a variety of players. As far as I can tell theres about 30-50 degrees difference in dry boiling points (270-320ish).

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
