Sorry I cant make it either Richo.

Got a new Brake Master Cylinder put on today. A bigger, better, larger unit to suit the Brembo's. BM57. (Bigger than 1")

Instead of the BM50 for the Sumitomos (1")

Now I have braking issues - Again :(

Booked in again Wednesday to get it looked at.

Stocker should work fine with the Brembos. But then so should BM57, what's the issue?

The stocker became spongy when I had the New rotors and Brembo calipers put on. Pedders put the rear calipers on the wrong side therefore the bleed valve was opposite to where it shouldve been and air got stuck. :(. Took it back twice and they didnt work it out. Took it around the corner to ACT brakes and within 1 minute they told me the problem. So they put them on the right sides and up the right way bled, and all good.

Because I put the Bremo's on I bought the BM57 to suit. Today ACT Brakes put it on and I am back to spongy.

When the ehgine isnt on the brake peddel is hard. Turn the engine on and they go instantly spongy.So doesnt appear to be air trapped in system.

So anyway - back to ACT brakes on Wednesday. If they cant resolve within the day I'll get them to put the BM50 on. As it turned out to be very good.

I thought I'd get better stopping with the match of Brembo calipers and the BM57 like the Vspec I and II.

The bigger BM57 will give you slightly shorter pedal travel and a harder pedal so while the stocker will decrease harness and increase travel it shouldn't be excessive or spongy. The movement when you turn the engine on is it 'sponginess' or 'travel' because the booster is getting vacuum?

The booster appears to get vacuum as it should but the sponginess is more than should be.

There should be a point where the pressure increases and then goes fairly hard as the brakes are applied

I dont get to the hard bit and the first half is soft like there is no pressure.

Any ideas ??

The other thing that annoys me is that every brake shop discounts bleeding the ABS without reason - Why is that?

It connects directly to the BMC, it has the capacity to trap air, it's higher than the calipers and higher than anything else in the brake system (except the BMC which is pretty much at the same level), it has bleed valves on top of it !

I'm not a brake specialist BUT i am mechanicaly minded and logical.

Faulty valve or torn diaphragm?

So how many of you keen to go for a drive this comming weekend ??

Thinking of grabbing a big breaky in Cooma (1hr away) then maybe a short stop at Jindy for photo op and then lunch at Charlottes private parts.

Maybe even cold drinks when we get back

Following weekend is Wheels @ old parly house.

I won't do it this weekend, doing Motorkhana on Sunday.

But I was close to driving out that way last weekend (Canberra long weekend) until the R32 engine died while out and about. Anyway that got me wondering if any of the roads up there had been closed from the recent rain? A majority of the fun roads were closed and we found out for good reason.

      Has anyone put in brand new full carpet? (not floor mats)

      By Yeetus · Posted

      Only needed to pull out the seats, center console and gear shifter surround, took a weekend and a fair few beers. You get to look forward to finding all sorts of weird shit under the seats and carpet, I pulled out a Chinese dudes passport from 2003, 220 yen and a condom wrapper 😆

      Well, turns out not a lot happened from back then to now, between life again, and working on 3 separate other cars (only one of which was mine, and will now be departing the household soon).   So I decided with the whole "don't go outside, it's a cyclone!" Turning in to being not a whole lot, I ventured down to the garage, found a couple of water leaks in the shed (the main one I've already fixed), and then ended up "stuck" as it started pouring rain, and I didn't want to walk back inside in the pouring rain. This meant I ended up taking a look at the Skyline, and trying to work out what past Matt had been upto. I retraced a few things out from scratch, added the rest of the power feeds in that I needed for the indicators, and headlights. Double checked I'd wired a few things up correctly (and worked out how I wired a few things to begin with), updated my sparse notes. Added one of the ground points. Oh, and got really really dusty, as the car is quite dirty. Wrote up quickly what should be left for me to do with the wiring too. Adding the below photos more for my records than anything else. I need to make myself a proper book for the car that details everything, and how I've done it, but for now, this is my records... The third image is my most important one for me, and I need to draw it out into a proper schematic eventually. The last photo is my re-written list, I'd have put it on the white board, except I had to take the white board down to fix one of the water leaks.
