Improvement of brakes.

Equipped with a small set of brake straightening tools, I started considering the options.

From left to right: Celsior 21; 33 rock; 81 stock mark.

So candidate number 1 is Celsior.

The disk is 315x27 in condition like new ones.

Looseness on the hub about 1.5-2mm

After spinning and rotating, I realized that the spacers would be tricky, the brake disc wobbles on the hub, there will be a lot of hassle during installation, so I didn't bother and threw them away with the Kresta JZX100.

Candidate number 3 is hard to call a candidate since it's stock from GX81.

The set with new pads and zero wear, the caliper was weighed and I immediately picked it up for better times or people.

Candidate number 2: 33 SKALA ECR vs 32GTR.

A bit more detailed here.

On the left is 33ECR 296x30, on the right is 32GTR 296x32

Now they are just switched around: on the left is 32 and on the right is 33

33 ECR

32 GTR

It turned out that the diameter of 32 and 33 is the same, 296mm, while the thickness of the disk for 32 is 32mm (a small tautology came out, but it's memorable) which is 2mm thicker than its younger counterpart. And the most interesting part: a heavier disk weighs less by about a kilogram due to fewer ribs and there's no extra non-working area inside the disk.

Then disappointment happened…

I wanted to install a thicker and lighter disc, but it turned out that their shafts differ by 1mm leading to spacers not fitting in thickness. One pad would hang loose while another would squeeze the disk preventing its rotation.

So I had to settle for the set from 33.

Then came into play mud flaps from a UAZ car

After bleeding and tests, I'm satisfied with my choice. Now I can not only accelerate well and brake just as good, but also just standing at a traffic light spin rear wheels up to redline and shave off several millimeters of asphalt :)
