Disco and RRC have a deceleration valve on the inner wing below the master cylinder, or you could fit one of the load sensitive brake bias valves found under the back of Transits (kit-cars use them to make bias brake systems).

But as for the master cylinder, I doubt it.  They all have the same bore for primary and secondary circuit so unless the Defender has a different bore to the Disco altogether you can keep the one you have.

just bang it on and bolt it up Kev.

there is some truth on the bios and the back does lock up slightly before the front but mine been a truck cab I expected that, to be honest it works well as I can still steer a little first, I call it ABS LOL :dance:

Well, if the front lock up first you cant steer.  i prefer mine to lock up rear first  :lol:

Fortunatley for me then that Norfolk is so far away :D

Once the tyre stops spinning it actually has less grip, so as observed above it is better to have ther front wheels lock up and the backones turning so that the car will stay straight, if the back end locks up first it will try to pass you.

Yeah, but if they lock up on a corner you are f****d,  plus, having rear wheels locking up first means i can get some great drifts on damp roads, even onto the A11  :twisted: :twisted: :twisted:

Over steer v Under steer

My preference is under steer, far more predictable and the you have a far bigger crumple zone in front of you than too the sides. Some people can drift very well and could catch a spin in all conditions, though my experience is that the majority of drivers are not that good (my self included). I have "drifted" vehicles intentionally, but I wouldn't want to do it near the public highway. I know enough people that have come to grief doing stuff like that including one 90 being drifting into oncoming trafic and getting T boned.


If you do lock up then use cadence braking to retain control, its like DIY ABS and although it involves releasing the brakes, its still a lot better than keeping the wheels locked up in a skid.

Drifting is great fun in my 90.
Been doing it since i could drive it. Learnt in a muddy field on a farm and then on a wet airstrip, i have no worries about my personal control of the car. i dont do it when other people are about for the obvious reasons.
Still, def prefer oversteer to understeer, make the drive more fun  :twisted:
