Rear Brakes Locking before front JZA80

[AndyTTR]

Thank you for the detailed explanation OC, greatly appreciated! (will rep once I've spread enough to rep again).

Glenn - If you're looking at swapping to the 2 piston rears you could try import monster, there's always a few sets of 2nd hand rears selling separately on yahoo.jp... Also try Koffee_black's trader forum on the supraforums (Gorilla Industries), he was selling reconditioned callipers a while back.

not as easy as it sounds. Where am i going to find just rear calipers? And im not sure i want to buy a set just to get the rears then have a spare set of fronts??

Wonder if i can get just rears from toyota?

Sure is. As you said, just buy them from Toyota. I got brand new front and rear calipers, freighted to Perth from NZ for $1100. I'd say a large chunk of that was the fronts. I then sourced the rotors locally for like $200.

rory at rutherford and bond should be able to hook you up with a set of rear calipers...

he is in nz but prices are generally very competitive/awesome

thats his email address... you will need either part numbers or vin/chassis of a car with the 4/2 pot brakes

This is the man I got mine from

ok thanks guys will see how i go with getting some rear calipers and rotors. bit gay considering i just put new pads and rotors in them

oh well better than having a massive accident on the track i guess.

rep has been spead. thanks guys

I'm sure you'll find someone who wants new pads and rotors for their 2/1 setup dude

Just thought id ask, may be a stupid question, but have you greased the slides etc on the rear calipers? do they slide freely and return properly? Alot of imports get moisture in the slides and rust up and bind, and also the extra heat from the racetrack can destroy the grease and it gunks up.
Im guessing you may have tried, but with the rear end jacked up, can you turn both rear wheels freely and evenly by hand?

havent tried that or regreased them to be honest. Replaced the pads recently and had no trouble moving them. Although by the looks of all the fancy maths above from what i understand of it (i could have totally misunderstood) but i am getting the same, or at least close to, the same braking pressure problem is its over a smaller surface area?? Is that it boys or did i totally miss the mark??

Also the hunt for rear calipers isnt going well so far, it has only been 1 day but not looking good as the reco'd are not available and new ones quoted price is 620 a side.

Where was that quote from!?

[1jz68u]

forum sponsor amayama. Though i would try them first. Apparently toyota are still making them also. They are out of 1 side and are making more.

toyota NZ cost me somewhere around $1500 shipped for a full set of 4 big brake calipers

[JustCallMeOrlando]

Ahh okay. Haha, mine were a bargain then!

the caliper you have now (1pot), has more braking force than the 2 pot. not due to pad area, just due to piston size and disc size.

pad area helps with heat and consistency and wear etc, but the braking force should not be drastically affected by pad area (in this simple comparison..)

both sides (this guy usually has higher local shipping costs tho)

man i was trying to use the importmonster yahoo search and it was being super gay.

thanks for the links, is it possible to workout how much the shipping would be to my door?

and im sure they will sell for more than $40??


you have the advantage of being able to read japanese dont you?

it would appear i need to give some more people rep before giving you any more
