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:

       Toyota Corolla Levin 16 1998       Toyota Corolla Levin 16 1998

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:

       Toyota Corolla Levin 16 1998

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:

       Toyota Corolla Levin 16 1998

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:

       Toyota Corolla Levin 16 1998

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. :)

You are a handy person. I can't do that myself. Respect

l
levin24 03.02.22

I agree with you, but in my opinion there is a weaker point - this is the attachment of the caliper to the adapter.

4AGent 03.02.22

Yes, it is a margin of safety - the disc is 3mm thinner on the side!

l
levin24 03.02.22

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?

4AGent 03.02.22

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.

levin24 03.02.22

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 :)

a
apache 03.02.22

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)

U
URS190 03.02.22

yeah. They won't fit all 16's. But they slow down terribly)

l
levin24 03.02.22

Yes, they also say rims for 16 are necessary, otherwise they won’t fit.

U
URS190 03.02.22

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.

l
levin24 03.02.22

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.

U
URS190 03.02.22

Gemorno however. Add a penny and you can use the GT handicap. For handiness offset!

l
levin24 03.02.22

Can you tell me more, or can you show a photo of what exactly you turned?

i
il4 03.02.22

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

l
levin24 03.02.22

And how much after the groove did it turn out?

i
il4 03.02.22

pierced

l
levin24 03.02.22

Did you fit a 25mm disc into the caliper? Or did you grind it?

i
il4 03.02.22

- 12 mm, under our native caliper mounting bolts
- disc 275x25mm

l
levin24 03.02.22

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

i
il4 03.02.22

and this is how I do it :)

l
levin24 03.02.22

Ah, I got it! Thanks!
It will be necessary to grind on their own, so that new disks can be installed))

Thanks for the advice! I will be careful! )

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!

l
levin24 03.02.22

Wow! Great! And I keep licking my lips on the C160, but I don’t decide how ...

Y
YLevin 03.02.22

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!

l
levin24 03.02.22

What are your plans for transmission? Or a secret? :)

Y
YLevin 03.02.22

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.

l
levin24 03.02.22

So you have already decided on this option?

Y
YLevin 03.02.22

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.

l
levin24 03.02.22

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?

Y
YLevin 03.02.22

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 ...
cgi.ebay.com/ebaymotors/N...19QQptZRaceQ5fCarQ5fParts
only the adapters need to be machined and the disks are stronger than stock orders.

Well, the pads for these calipers:

levin24 03.02.22

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.

s
sewa88 03.02.22

Directly, more disk is more resistant to overheating, isn't it?

l
levin24 03.02.22

And how is the size of the disk and resistance to overheating related? :D

s
sewa88 03.02.22

Tell me, because with brakes from rx7, a brake disc from sss is installed, then in fact the brakes are no more resistant to overheating than SSS? how are they better then?

d
dead995 03.02.22

Yes, brakes are key.
