Brakes from Ryksa on Mac :o) - Toyota Corolla Levin, 1.6 liter, 1998
My stock front single-piston brakes struggled with the 4A-FE. After installing the ZDT ( www.drive2.ru/cars/toyota...4062246863888377515/#post ) the situation improved, but it was clear that such a brake system was not enough for black.
Accidentally discovered a report on the installation of brakes from the Mazda RX-7 ( www.drive2.ru/cars/toyota...4062246863888223448/#post
) I fell ill with this idea.
Just in a couple of days I found at the auction:
Pleased that the kit included hoses and pads.
We remove the stiffeners, partially cut off the ears of attachment to the hub and drill holes:
We cut the bracket from the stock brakes in a suitable way, make holes and cut the thread:
We make spacers to center the brake disc relative to the side surfaces of the caliper, and accordingly the pads:
Lubricate the connections with thread lock before final assembly. We managed to put the bolts only on 10mm - there was not enough metal for more.
And this caliper was the first to be redesigned. Hastened and removed more metal than required:
Therefore, I had to put on two bolts - 8 and 6 mm on each side:
This is what it looks like on the hub:
I put the hoses from the Mazda, they stood up like family:
Brake disc from SSS, diameter 275 mm, thickness after turning turned out to be 19 mm:
The rim (15 "7x35) got into grinding. Literally 10 mm left from the caliper to the disk.
I felt the benefits already at the installation stage. These calipers are lighter than stock calipers (although you can't tell by looking at them) because they're made of aluminum alloy. And another plus - the pads can be changed without unscrewing the calipers.
How they slow down is just a fairy tale! Several orders of magnitude more efficient!
The reliability of the design at first raised great doubts, but so far no problems have been identified for 1.5 months of operation. With these calipers, this is the first time I've braked with a whistle on the pavement, and this is on Adrenaline from the Bridges.
In general, I'm happy as a boa constrictor :)
Z.Y. Everything cost 12 rubles, which in my opinion is not expensive at all.
Thanks a lot! I had to collective farm, because by and large there was no other way out. The hardest part for me was to drill the holes accurately as I don't have a drill press. Friends helped out, and not only in this, for which I thank them very much. :)
I agree with you, but in my opinion there is a weaker point - this is the attachment of the caliper to the adapter.
Thanks!
On those disks that fell into my hands, the wear was much greater - about 4 mm.
What specifically bothers you about 19mm? A smaller margin of safety of the disk or something else?
Great job, but I'm still very puzzled by the thickness of the "discs after turning" - 19 mm. Strat discs 25mm wear 2mm max. Rhsky calipers seem to be on a 22 mm disk, pioneers like it bore a little so that 25 mm fit. But I wouldn't ride on 19mm wheels.
10mm from caliper to disc is fine.
Thanks to!
Do you mean that it had to be done before the swap? If yes, then this was done while the car was in the garage and waiting for the exhaust pipe (I did not immediately post the report). Therefore, my black on other brakes didn’t drive :)
And I also need to twist the back number on the bumper - and everything’s okay, you have to take it off :)
It was necessary to start with this)
well done, in a word, you are a handy type) I can’t even drill a hole in the bumper for the license plate for the second month, but you assembled the car)
And damn (You have 4 holes in the wheels then. You have a handicap of 5. It won’t work. You’ll also have to go out of your way.
Thanks! I agree, it's not a lot of crap. Alas, I didn’t know about the option from the GT handicap, tell me where you can find the extra. info.
so I didn’t grind the discs, but the calipers)
bored the opening for the disc up to 30mm on the lathe,
new 15.5 mm pads stand up with a bang, without plates
Very technological! I myself can't do that.
There are a few questions:
- the diameter of the holes that you drill in the caliper
- the diameter and thickness of the brake disc
Ah, I got it! Thanks!
It will be necessary to grind on their own, so that new disks can be installed))
here you can see

the plane in the caliper, between which the brake disc
at first made finally a grinder)
The main thing, when you decide, see that it was with a block!
Many of them went without it, for example, on the BZG restyled, on the Ranks, Fielders!
Yes, it's not a secret, it's just not willing to jinx it.
I took the Flywheel for 4.7 kg, the Torsen blocking from the BZR,
upgrade the clutch to a new one (basket, disc, release bearing),
and with synchronizers with their clutches, a small hybrid from a different type of box,
so that the oil could be filled in later than the turbojet engine (otherwise in winter it is generally a stake).
Plus, in C56, the main single bearing quickly ends, they will put a double one.
In general, our Khabarovsk rallists will do it according to their own recipe. Boxes after them race very well!
Well, so far I have not found a more suitable option for myself.
But this is not going to be soon, now there are a few other troubles in terms of transmission and suspension.
Thank you =)
I already found it, I didn’t know that you were away for a long time.
As for the brakes, you also choose in the same place what thickness of the caliper disc (0.81 1.00, etc. ...), it is this 1.00 size that is probably in inches, that is, for a 25mm disc, but the shape of the caliper shows that the block will not fly out! It is generally laid in the caliper from above. There, according to the link below, the drawing of the caliper goes.
Hey!
About the rating - yes, there is such a thing, but this is not the main thing :)
I measured the diameter of my former stock ones yesterday - 258 mm turned out.
Good option you looked at. On which disc such a caliper will sit, do you know? Or are you actually planning to customize and look at the options?
Hey!
Something you completely rolled back from the first lines! Disorder! But the girl on the stock unit among the first! Stupid system here! Okay, I didn't come here to ask.
Remind me please the diameter of the front brake discs on the MAC?
That's what I found, I think ...

only the adapters need to be machined and the disks are stronger than stock orders.
Well, the pads for these calipers:

In theory, other things being equal, maybe. But in practice, there are many more factors such as caliper design, brake fluid, disc size, brake pads, etc.
