    raff if i was you after seeing your picture of handbrake i would mount that cylinder up the right way so the pipes come in the top of the cylinder , in your pic it is mounted upside down you will get mega air locks like that.

    Raff, if yours is a 180, try putting 200sx rear brake setup on it. I did it last week on mine (got the rear hub assemblies complete with calipers, discs, handbrake cables etc for £20 off a scrapper) and the handbrake is awesome now. I'm going to take the hydraulic one off when I get time, as all it does it sit there looking pretty and getting in the way.

    Without any major work, is there any other ways of helping the rears lock easily when using a hydro handbrake?

    ive always wanted a hbydraulic handbrake its not fair!,yea tried mounting it the other way and still no difference, and without a doubt theres no air in it,if i thought new pads and discs would sort it i would buy them but it just feels like shit,loads of people on here have hydraulic handbrakes how do any of them work,do s14 calipers fit on the back? i know id loose the cable handbrake but dont care

    If yours is a 180, you'll already have S14 brakes on the back.

    I have a 180sx and I've done an R33 GTS-T Skyline hub conversion to it I put a hydraulic handbrake in it and have set it up to run dual calipers on the rear. The hydraulic handbrake runs it's own separate line to the calipers on the rear but I can't lock it up I can slow it down and it's been bleed at a shop by a mechanic the foot brakes front and back work fine but the hydro is real hard too pull up, The mechanic doesn't do a lot of work on modded cars so he doesn't know why the hydro wont work.

    Look at which size cilinder you've got. I assume the brake pads are fine, cilinders work properly, system has no oil in it. and discs are clean.


    Big cilinder = small throw and low pressure to caliper.
    Small cilinder = Bigger throw and higher pressure to caliper.

    Because the bore on the small cilinder is less you'll have to move the handle more to move the same ammount of oil as the big cilinder. But The force you're applying on the handle will push on a smaller area of oil and therefore increase pressure.

    Hydraulic handbrakes aren't equal. What one have you used

    If you try and bleed it again and there is definitely no air and all fittings are tight (and not broken - yes it's a thing) then switch to a Wilwood 5/8" instead of the default 3/4" size
