Well I’ve spent all morning and half the afternoon trying to get some pressure in the rear brake. Thought it would have been easy with the direct line from master cylinder to caliper - lines are full and there’s no air anywhere but the lever is still soft with full travel & the pistons aren’t closing. Already had the caliper apart with the pistons out, pulled the master cylinder in pieces and nothing wrong with it so I’m lost.
Any suggestions will be most appreciated.

Did you take the rear caliper off and elevate it above the master for bleeding? Place an object with flat sides slightly wider than the rotor to keep the pads wider than the rotor under pressure. This is more or less how the bleed is done in the manual.

The other option is to reverse bleed, which is to inject the fluid through the bleeder and stopping when you fill the res.

Thanks @bp_SFV4, done all that and yeh the whole system is flushed so no air is coming out of the caliper. There’s just no pressure which is frustrating coz the whole point of deleting the abs and redoing this was to simplify things so this wouldn’t happen

Did you try the reverse bleed where you'd be injecting the fluid, in an empty system, through the bleed nipple?
I don’t know what suddenly happened but I took the dog for a quick walk then thought maybe I can crack the banjo at the caliper to make sure there’s no air lock in the line and try again.
Success! Did that, then re-bled from the nipple, one big air bubble came out. Next press of the lever she came good, still some improvement to be found somewhere as I’d like to reduce the lever movement a little further but got a result for now.
Cheers for the tips 🙏🏻

Was hoping to make it down for the 13th & 14th to give it all a good run and see how the new brakes feel but our shearers bloody decided to postpone a week so gonna miss those unfortunately :cautious: Will be back to watch ASBK and ride after that 👌

Stop fast parts and new wheel all attached after ordering the wrong ti rear disc bolts and waiting to get back to the dealer who ordered my front bolts for me, nice little glimpse of silver thru the wheel there, will see if it does good skids on Tuesday when I’m back at the track 😈

(giving the metzeler RR 200/60 a go this time - see what change I notice from the 200/55)

Also decided to just remove the fan, saves a bit of space down low and make accessing the front manifold easier should I want to fiddle.

As there’s no options for race seats that I liked the look of (+ save myself $500 or so) I decided to make my own while I was feeling creative. Ran out of resin but got the basic shape I’m after so now just reinforce the dog, figger out a way to mount it and add a pad then I’ll pretty much have the ergonomics sorted 🤞🏻

Smsp review 14/3/23 - it was wet, I managed 5 laps before we got flooded lol.
No chance to get used to the new brakes but the stopping power on the T-drives compared to oem is unreal. I was probably a few seconds down from usual because each corner I’d scrub off more speed than I’m used to much quicker and then be idling for 1/2 a second through the turn before I could pick up the throttle again. Will need a full day to adjust nek time.
Monkey grip tank entender was a big + too. Hanging off was a breeze, so once I have the new seat I reckon Jack Miller better watch out 😆

Granted I'm sure you're a lot faster than me, but I've never read such a glowing endorsement of T-Drive rotors.

There’s two things I can think of for what I was noticing. Because they’re slightly thicker more heat is maintained - so what I’m experiencing there is a stronger initial bite than I’m used to + the shorter travel for the pistons in the caliper so less force required on the lever. Will upgrade the pads soon as well and see what else I can notice

New seat done, quality is right in line with products from the corse department 😂
Quite enjoyed coming up with this one, next job: full aero kit with spoiler and ground effect fairings 😝 lol.
