Rolaspec Posted February 18, 2016 Report Posted February 18, 2016 Just wondering if I need to upgrade master cylinder size for a hilux caliper conversion in ke30 if so is a 1inch to large or will that be ok. Cheers Quote
Banjo Posted February 18, 2016 Report Posted February 18, 2016 (edited) Hi Steve, Most Rollaclub guys who upgrade their front brake rotors & calipers, also increase the capacity of their master cylinder to avoid a very hard pedal. Master cylinders with 15/16" or 1.0" dia. cylinders work well. I used a Pajero MC, and it worked fine. Brand new ones on ebay were relatively cheap. You could do the conversion in two stages. Upgrade the brakes, and see how "hard" the brake pedal force required is with your existing MC. If it is too hard then upgrade the MC also. I did similar upgrade a couple of years ago. I used Cressida rotors & calipers, + the Pajero MC. The braking performance of the car was greatly improved, and it has worked perfectly. I've currently got a KE55 complete rear diff assembly & 9.0" brakes ready to go in, to finalise the complete brake upgrade. Only thing to consider, is whether you want to upgrade the booster also. However, it gets very tight in that area, if you go to a bigger booster + MC. I stuck with the KE30 one. http://www.rollaclub...page__hl__banjo http://www.rollaclub.com/board/topic/70150-problems-after-paj-master-cyl-install/page__p__686736__hl__+pajero#entry686736 Cheers Banjo O Edited February 18, 2016 by Banjo Quote

JasonKE55 Posted February 21, 2016 Report Posted February 21, 2016 Hey fellas, i'm currently doing an SR conversion in my Ke55 and my brake master is having issues with clearance of the manifold. Are there any masters with different inlet positions ie on the bottom that would still bolt onto my standard booster?? Cheers Quote
oh what a nissan feeling! Posted February 21, 2016 Report Posted February 21, 2016 (edited) Is your engine s13 or s14. What mounts are using? Edited February 21, 2016 by oh what a nissan feeling! Quote
JasonKE55 Posted February 21, 2016 Report Posted February 21, 2016 S13 and mounts are from Jordan Quote
BUZ440 Posted February 21, 2016 Report Posted February 21, 2016 S13 and mounts are from Jordan Jordan does a hydro pedal box conversion on exchange of your own unit, hit him up Quote
JasonKE55 Posted February 21, 2016 Report Posted February 21, 2016 Jordan does a hydro clutch conversion. The brakes stay the same. I just need to figure out which master to use Quote
oh what a nissan feeling! Posted February 22, 2016 Report Posted February 22, 2016 (edited) the commodore master i use is identical externally to the standard ke55 one and mounts to the ke55 brake booster. it is internally 15/16. when i had a standard intake on mine it was tight on that side but fitted fine with more than 10mm clearance. talk to jordan, the kit may be made to work with the ke30 brake master and booster which is a much smaller setup.

JasonKE55 Posted February 22, 2016 Report Posted February 22, 2016 How did you set up your brake lines then? The side brake line is very close unless I use a banjo bolt or something like that. Also I'll have to remove the proportioning valve switch as that hits and also the bleed nipple hits so I'll have to chop the top off Quote
oh what a nissan feeling! Posted February 22, 2016 Report Posted February 22, 2016 It sounds like your engine is positioned slightly different to mine. I don't have the brake light switch connected, but the rest is normal. Your best bet would be to use the master and booster off an early ke30 i guess, it will give the clearance you need. As an upgrade that will bolt to that booster a pajero master cylinder is often used. Quote
Rolaspec Posted February 22, 2016 Author Report Posted February 22, 2016 Hey do you know what model (year) pajero Quote
oh what a nissan feeling! Posted February 22, 2016 Report Posted February 22, 2016 Series 2 paj, nh to nj. So 92 to 95 probably all the way to 2000 as well but i havnt checked. Quote
Rolaspec Posted February 22, 2016 Author Report Posted February 22, 2016 Ok sweet, I have a wilwood compact but it's not going to fit, so going to source a paj one Quote
Banjo Posted February 23, 2016 Report Posted February 23, 2016 (edited) Hi Steve, There are several varieties of the Pajero MC. The differences are the outlet position for the front brakes. The model you need is a JB1712, which can be obtained on line at ebay. Cheers Banjo Edited February 23, 2016 by Banjo Quote
