I ve just fitted your hydeo lines to my s14a. All fits ok. I ve fitted them the same way in your picture keeping abs pump and standard 14a t piece and the hydro doesnt lock the rear wheels. Do I need to change the rear t piece?
Grooved discs. Not sure what pads but loads left on them. The hydro is a 0.625 master cylinder. Standard calipers.
Probably needs bleeding some more mate, s14 rear brakes are the best but should still lock up with a good tug! lol
All boils down to 1) how good your rear brakes are (caliper condition, pads/discs) 2) how you're using it. Does it feel ok? As in firm when you pull it? Apparently the rear T has a restrictor in it, never looked myself though.
Hydro sorted. Handbrake cables to tight. Slack them right off. Warmed the rear brakes. Hydro now locks.
