On the track the S2 brakes do not have the feel of the S1. My car is post 06 so does not have dead travel. They just feel like there is too much servo and the Abs kicks in way too early. However, despite the FLSH i did boil the brake fluid and the front pads came apart. I also noticed that the old pads, not branded but said TXE on them, made so much dust it filled the vent holes in the disks.
I now have race fluid, braided hoses, cleaned discs and pagid pads, so they should feel better. Anything else I can do? They are very powerful, just lack feedback. Or am I just clog footed after an S1…where you really have to stand on the brakes.
Did you boil the fluid at Donnington ??? If so , that’s pretty normal if your trying hard/racing , it’s the hardest circuit on brakes in the UK. A change to racing fluid will have helped, but a servo always reducing pedal feel, continual use over time , will get you used to them/it
Erh hmm…boiled at Bedford. It was a hot day, the discs are now a bit blue. I now have high temp fluid. I think I may just be clog footed, you really have to stamp and push on an S1, I have got used to that.
To increase pedal feel and get rid of the slight spongy feel you need to invest in braided hoses decent pads and the right fluid.
If this does not give you enough braking power then larger front rotors is next. Then to 4 pot fronts and lastly the old 2 pots from the front on the back.
Ever since I changed to Motul RBF 600 and put on the 308mm rotors and 4 pots and performance friction pads I have never had brake fade
Yes but you cant just turn it off, you need to get rid of the servo aswell or you will end up locking the fronts at low speeds with little or no feel of it happenong on the pedal
Yep, I sold the Yota S2 and bought a Honda powered S2 Elige, k series chassis, non servo brakes, 80 kg lighter and more ponies. ))
Sorry, I know that’s not the answer you’re looking for. I looked at going non servo on the Yota but meant changing the pedal box, changing electronic throttle… A lot of hassle
never had a problem with mine turned of on or off track, I used to disconnect one of the sensor at tracks where I found it intrusive due to bumpy braking zones. I always find it useful to have it on wet trackdays as it does save you then, as I put earlier I have no problem with the feel of the brakes, but you do need to change quite a lot of bits to make it work.

Plus 1 to the braided hoses, had mine done earlier this year and they do make a decent difference for a pretty low cost.
Bigger brakes is on the list after I get my suspension sorted
Aparently it was 829kg when last weighed. I have stripped plenty out since then but had to fit other stuff as well e.g cage.
On my last Yota Exige I ran all the time with the front ABS sensor disconnected to disable it. I always found it ok on track and stage without too much lock up, although I agree it’s not as easy to finesse as a non servo setup.
The main reason I looked at going back to non servo was weight reduction as there’s some reasonable mass in the servo and abs units.
Having said that I’m expecting a nice delivery from Dave soon with a set of AP 4 pots and 308 discs I blame jonnyfox for that after letting me drive his car back to back at Donny
I’ll keep hold of the front 2 pots in case Ade convinces me that I need to put those on the rear as well.
I wonder if the lack of feel I complain about is because the brake pedal is so much higher than the gas pedal? The is no way you can H&T without flippers for feet or REALLY using heal and toe. I hope I can adjust the pedal height by hanging upside down and adjusting the master cylinder push rod?
Currenty, by the time the pedals are at the same height the brakes are on pretty hard
My thoughts on ABS …
I’ll try to keep it short …
If all goes terribly wrong (as it does) … The ability to lock all 4,s is a godsend,and will see an out of shape car slide to a stop harmlessly…
Throw in ABS however and that ability is lost … If you lose it proper and are pointing at the barrier then you will hit it …
…
That’s my reason for pulling the ABS fuse on track /road…
…spose I’m talkin crap !
I had a very unpleasant braking incident 2 years ago at the N�rburgring (in the section Pflanzgarten I): After the little jump, I waited for the car’s suspension to settle before I hit the brakes to decelerate for the upcoming double right bender. Nevertheless the ABS kicked in (bumpy surface?) and the stopping distance greatly increased. The right bender came closer VERY quickly and my heart leaped into my mouth. Fortunately these little plastic cars can corner so very well and I made it through the bend in one piece.
My main concern with disabling the ABS is the following: if I deactivated the unit, would I still be covered by my insurance? I guess not…
Wes whats yours tip the scales at?
