Sorry for the delayed response guys but we managed to get it sorted! Turns out there was so much air in the lines it just took hours of bleeding to remove as much air as possible. Not sure if some air was stuck at the high point of the lines where the ABS system was or not Ended up using a friend’s suction type bleeder at the nipple end. We kept the nipple closed, he pumped up the handheld suction bleeder while I pumped the pedal and we did quick releases of the nipple which managed to get the air out. Did this a few times on all 4 starting from the rear passenger’s side and got it working Definitely took some time but got there in the end and now the feeling is super firm Brakes have been bedded in and grab super well once warmed up. Lots of brake dust from the fronts, as expected, after a hills run DBA T3 Rotors / Endless MX72 Plus Pads / GKTech Braided lines (Hard line delete) for anyone wondering

Thanks for the info. Defiantly sounds like a failed seal or something similar just took a video of it now for reference IMG_2625.mov

Hi all, 1997 R33 GTST with ABS Have a question regarding brake bleeding as this is the first time ive attempted it. Changed over my rotors, pads and to braided lines all in one hit and am at the stage of bleeding the brakes and have noticed that there is now a hiss sound coming from the brake pedal/engine bay area (as well as not firm) after the first bleeding process (1L of fluid added give or take, some may have recirculated into the bottle). Certinatly got air in the lines during the changeover process. Seems like there are no bubbles coming from the bleeding nipples but definatly have a spongey feel to the pedal and definatly isnt drivable. When bleeding, it builds up plenty of pressure and as the nipple is release, with my foot down on the brake pedal, it continues a slight bit more before re pumping In terms of the ABS system, is there something that should have been done prior to bleeding, like disconnecting it ? Is the hiss noise, that isnt something I noticed prior a damaged part or is that the air moving through the lines somewhere near the ABS ? Is this just a case of needing to do more bleeding ? Brakes were working fine prior to this (other than being worn) and have checked everything ive touched in regards to being tight. Rolled the car back and fourth and the pads do grab (but with the foot all the way down on the brake) Thanks

I’m also in the market for some Rpf1s for my 33 gtst, non-rolled guards and going to keep them that way. Advice on sizing and any pictures of what anyone’s running will be a big help, as I’m no guru on fitment… 😬
