I am with you on this one but I will worry about it when I cross that bridge and I have a pretty good idea on how I do it. Once I have everything on I can do a small write up to help others out.

The rebuild kit cost is like $74 from the dealership and this part number does not cross over to Toyota.

What all was in that rebuild kit? I can't remember how much mine cost, but looking at the part number now it shows $42.23 on Sewell.

the kit comes with gaskets for the brake line banjo bolt, 8 square cut seals, and 8 dust covers and lub to install everything. I work at a Toyota dealer so I got my kit for $30

Thanks guys. I picked up a set of LS400 calipers off a 97 LS400 that was being parted for parts,and they look to be in great shape! Luckily the guy lived 10 mins from me and got them for dirt cheap.

I'm just going to be gathering all the parts for the install as well as rebiuld the calipers. Better to have piece of mind I think.

On a sidenote, I have 18" wheels with 42 offset in the front. Will those clear okay? Or do i still need a spacer?

Why mod, when you can ride STOCK...at 11 psi

Its not about the offset its more to do with the xfactor of the spokes. The shape of the spole defines the clearance not the offset.

100% right, I have 17x8 +45 Enkie RPF-1's and they are cutting it super close.

how difficult is it to rebuild these calipers on your own? I'm trying to source the rebuild kit.

mainly, any tricks to removing the piston if you have no access to compressed air?


Fig I'm sending you a PM btw.

If you do not have access to an air compressor you can use a flat head screw driver and a channel lock of some sort. Teak the dust boot off and then use the screw driver to fry the piston up as high as it can go. Make sure you pry it up as equally as you can so it doesn't become cocked. Put the screw driver in the groove where the dust boot sits also. Once you can pry it up any higher this is where you use the channel lock to rotate/wiggle it out. Just be super super careful when you do this so you don't scratch or gouge the side of the piston. THIS IS A LAST RESORT IF YOU DO NOT HAVE AN AIR COMPRESSOR. Once its apart use a pick to hook the square cut seal and pull it out. When you install the new seal make sure you use a small lubricant to put on the seal so when you install the piston it doesn't catch the seal and tear it.

I think this may have been answered but after doing some research on SupraForums some people said you could use TT rotors with the LS400 calipers, can anyone confirm?
