About brakes. Need advice. - Toyota Corolla, 1.6L, 2004
As someone once correctly noted in one of the magazines of my childhood, competent debugging of a car always begins with the brake system.
For the Corolla, this is an iron rule along the way, since the brakes on it heat up just catastrophically.
It affects both the driving style and, apparently, the design feature, since the previous owner, who at the time of the sale of the second car in the family had a golf 4, mentioned that the brakes on the Corolla are not superb. I was clearly not embarrassed by this, because after our VAZ 10, albeit slightly modified, I had only one desire: "the shtob did not break."
Now I understand that I want more: "the shtob went" ...
Hence the question - who knows where you can get good ventilated brake discs with 4 x 100 bore holes and 2 or 4 piston calipers for relatively affordable money.
I was advised to use braking systems from project-Mu, but they are quite expensive, provided that I need brakes for everyday driving.

Change the brake fluid. If there is a lot of water in it, then the efficiency decreases from heating. Well, I can't believe that a working braking system cannot cope with 110 horses in a city! Or are you driving around the ring? :)
Braking efficiency drops. I also thought it was a malfunction. I thought that the discs are warming up because of the guide calipers, I disassembled them, changed the guides. better but still get warm.
Hmm ... getting hot or overheating? What exactly is the problem? Do you lose efficiency after several brakes? Maybe first you should check the pads, replace the brake fluid, and then change the brakes. IMHO, in the city to overheat the brakes by 1.6 ... this talent is needed.
you're laughing? :) It is recommended to change the brake system every 60,000. The brake fluid generally takes water into itself. my advice to you, start by replacing the brake.
I pierced the caliper guide - everything works fine.
It's just that efficiency is simply not enough, and not its fall from overheating.
And the rubber is now wider and with a larger radius.
It is not worth straining the stock parts to the limit, it is better to have a bit of stock.
I haven't replaced the brakes yet - I'm looking for a suitable option. I think you can find a 4X100 for an Audi or a Volkswagen or a Vase and fit it into a korollka on the front ... Yes, I would have at least two-piston calipers.
Replaced? I have the same problem. You just press on the brake and it does not slow down, the pedal is like dough, even the abs does not crack.
Well, for 15 rims (this is winter), summer for 16. The
brake "kruglyashi" will stand up without problems by 14 inches.
And it's more likely not about the disks, but about the brakes.
Replace the brake cylinder and refill with sports fluid - Beaver's advice was this.
The problem is precisely the feeling of braking.
If you sharply drop the speed, say from 140a, irritation appears.
It feels like the brakes are working to their limit.
Discomfort and slight vibration appear on the foot.
In this case, you need to think not only about the calipers, but also about increasing the diameter of the brake disc, because it is known from the physics course that the larger the lever, the greater the effort. An increase in the diameter of the brake disc will entail an increase in the diameter of the wheel disc and the purchase of new rubber. Thus, the budget for this improvement will exceed well over 100t.r.
Frankly, I deeply respect people who first of all care about safety and only then about increasing power, but you should still think about the advisability of this upgrade on this car.
Thanks for the budget advice, but I've already experimented with the pads.
There are hard Kashiyama in front, rubbing the disc hard, creaking, but not excrement in terms of efficiency.
Again, the question is in the initial efficiency and quality of braking.
Without replacing calipers and machines with two-piston ones, I'm afraid I won't find a decent solution.
