MR2 Brake master and proportioning upgrade

[TooF]

there is no air in the system its been throughly bled, there *shouldnt* be anything flexing they are all toyota steel calipers. all hoses are in good nick.

squishy probaly isnt the best way to put it. sub optimal pedal feel perhaps ? it just feels like its struggling to move sufficent fluid and hence required too much pedal travel.

Hey Josh, do you have the FD calipers already?
If not I have a pair sitting around here you can have.

And for those people looking at bigger bore MCs, MX73 & 83 MCs are 1" & 1 1/16" respectively & have the outlets facing the strut tower (iirc). MX83s are alloy & 73s are steel, but resleeving themm is usually easier than finding new replacements.

Yeah mate I'm buying a set of calipers off Linden.

I actually got the master that I used as it was listed as a substitute item for MX83, I knew the MX83 bolt pattern was right for my booster.

[TooF]

are you running the standard aw11 booster ?

[Joshstix]

Yep standard AW11 booster.

Just a bit of a re-dig here.

Been looking into bolt on options for the master Cylinders.

I looks like Hilux masters are the way to go. The 88-93 and the 93-97 models all had the outlets on the strut tower side the same as the AW11 and have the 4-hole mounting plate.

I have no idea of what the piston size is of these yet though... I'll keep digging.

[TooF]

JB1882 pbr part numebr from VZN130 (mid 90's v6 hilux) is a direct bolt on requring only minor bending on the factory pies to fit in place.

[MR22ZZ]

Do you know if it's a 15/16" or 1" piston?

[TooF]

1" and works a treat

[MR22ZZ]

awesome... that certainly looks on the cards then.

Im about to put in my setup, as soon as i have My rear calipers and have time to blast them,
I will be using a setup with these http://www.wilwood.com/Products/006-...4-PG/index.asp
To work out initail line pressures,
Put run it thought with stock bias, than no bias than with adjustable vlave and screw it to a rough estimate to begin with

Also what pads are people using,
I was thinking lucas or EBCs
Are both availabel for the calipers?

[TooF]

project Mu HC+ pads, worth every penny, put your foot on the brake and its like you've unleashed a parachute.

[merc-blue]

Toof any idea on there temp ranges,
Them project Mu sponsor or run a car in the national sports GT class, may go word them up at EC

[TooF]

they are rated from 0-800deg.. they work beautifully when cold. like a street pad really. then when hot they just imspire more and more confidence in the brakes.
these are the best pads ive ever used without question.

their couple of down points. they are dusty. not a big problem for me as i dont really care.

and when they are HOT they stink. they are one of the less pleasent smelling brake pads ive smelt. that said at any street speeds you dont get them hot enough to start smelling so not that big an issue anyway.

edit:

oh and they are distributed by Racer Industries who are also a sponsor of the NSW MR2 Club.

How do they cope at the track? Compared to say ebc greens? I'm due for pads and think i've been cooking the greens in longer sessions. You wouldn't happen to have a price and part no would you? (You're running superstrut twin piston right?)

ill be honest i havent had them to the track yet only street and some quick twisty roads, enough to get them hot but not quite track hot.

i would say they work better at cold then ebc greens and i havent had them hot enough to give an accurate opinion.

i wont give you my cost as i bought them though a sponsorship arrangement but they were a bit more then ebc a bit less then endless.

im running the ST165/ST185 (early) twin pistons which use a 258mm rotor. i dont know if this is the same as the super strut twin althogh id hazzard a guess.
their part catalogue is here
