Hydraulic Handbrake

i installed a hydraulic handbrake into my r34 its a racing logic one. Before i put it in i had a firm pedal. Since the handbrake has gone in the pedal is softer and takes longer to engage. I have bleed the brakes because i thaught that was the problem but it made no difference. I bled them from the foot pedal, do i need to bleed them from the handbrake? eg: instead of pushing on the pedal like normal pull on the handbrake? Would air get trapped in there as its a high spot? or would normal bleeding push it out?

The other thing is it does not lock up that well? i have to pull the lever fully up for it to lock (and only just locks up), others i have seen u could pull it only slighlty and it locks? this problem would probably be fixed by the above to?

thanks

Neil

You need to bleed it starting from the master cylinder if it ran dry at any stage during the install, then at the handbrake, and then at the 2 rear wheels and then back to the front wheels.

If the master didn't run dry then bleeding at the handbrake and then the rear calipers should do it.

I put a hydraulic handbrake into my car and had the same thing. It seems the handbrake killed my master cylinder.

In the end I found the handbrake was really hard to use - I ended up bending two handbrake bars as I had to reef on the handbrake so hard to get it to lock. So I since pissed the hydraulic system off and use good handbrake shoes (am currently using the URAS ones but have also tried the Project Mu ones and they seemed even better). But upgraded handbrake shoes definitely seems to work much better on a skyline than a hydraulic system does. (from my experience anyways)

ok i bleed every single point i could and got no air out. The pedal still feels the same and the handbrake still dusnt lock up. If i giv the handbrake a few short pulls before then really reef on it then they lock.

sooo i dont know maybe the master cylinder is shot? maybe the cylinder in the handbrake is?

its really shitting me now.

If i cant fix it mite look into these handbrake shoes, allthough that means i then need to get another lever for inside the car as i removed it.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      R32 GTS (RB20DE) Injectors Replacement

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
