Exactly bro...
Long story about today's up gradation of my car brake system..
1St of all I installed double face heat sink disc of 98 corolla...
After installing we faced the problem of clipper cover type thing which is placed at the bottom of the disc in the pic...that cover was narrow and the disc cannot be inserted in it..so we change that clipper bracket and get the bracket of corolla 98...then we realized (after fitting tyre )that the clipper bracket was rubbing with the rim after revolving the tyre so we grind it and make the size according to rim and then it revolves freely after the grinding therepy..
The job seem to be done . But after few miles on the way back to my home I smell burning of tyre..
I went back to mechanic and showed him the roasted tyres...
Previously When he was fitting the tyre then I told him that I am not satisfied with the revolution of tyre but he calm me by telling that sir g torra challa lo to free chally GA pir..
After burnt and hot rims incident we disassembled everything and then mechanic realised that we have to install the clipper along with pistons of 98 corolla so I bought whole pistons set ..
Overall...bracket...clipper along with pistons and discs ..everything's were changed today .
Discs 3500
Clipper along with pistons 2000
Now it's working perfectly...I realized that I was driving my car with 40% jammed brakes pistons...now I can feel the freedom ..lol
Handling is perfect now..
Sometimes I feel that breaks work when paddles are dipped down..but it work like charm...
No chuu chaa from breaks now..

[Hassan1991]

Great work bhai....now brakes will be amazing. Now your 86 have better braking then mien . Changing only disc never going to work....calliper of ae100 is greater so does the bracket.
Bhai also install ae100 brake booster. Don't change the master cylinder as both have same size.

[rockstar.mij]

Thanks bro..
In my car 88 corolla brake booster and 95 corolla calender is alreAdy installed..
Today I test my car on motorway and I observed 1St time smooth drive with better handling of car even at 130km/h.

[Hassan1991]

Great bhai.....can you send a pic of brake booster being installed.
And did you feel un balancing in brakes means car lean more towards front?

[m.haseeb.akram]

@Hassan1991; Yes Bro, U'r right, its not lowered, its as much stock as it can be, infact Pic ka bhii kamal itna nahii, Jitna maire heavy duty family ka haii in lowering it ...

[Hassan1991]

Hahahaha han gii or isi leya ma family nae bethata phir vo chalna jitni bhi nae rehti

[m.haseeb.akram]

True that, But these 86cees are durable rides, Made to last & its evident that we guys are still in love with our rides after a lapse of around 3 decades, not to mention the countless Man hours we spend with various Mechanics at Workshops to keep these beauties rollin.

[Hassan1991]

Absolutely and i'm slightly mad but i honestly and really appreciate you people whom are still using this beauty as a family car. Really now keeping this car and using it is hell difficult, one can't carry on without having attachment with his ride.

[rockstar.mij]

Correct @haseebakram we spent countless hours to keep it rolling on roads..but brother..every mechanical thing rolling on roads need maintenance..I oftentimes saw Honda rebon or gli corolla along motorway with bonnet lid open and desperately wait for help along the road...
I always show that sight to my dad who always criticize me about old cars and mechanics shoos relationships..
@Hassan1991 bro here is the pic.

[Hassan1991]

Thanks bhai.....yes that's ae90 booster, ae100 booster also fits....and did you change the proportional valve or it's same??

[rockstar.mij]

Calender is 96 corollas ..
And I think there is no proportional section used.
What is proportional valve?

[Hassan1991]

Gii cylinder is of ae100.
Bhai Proportional valve divides the pressure between front brakes and rear brakes it has a specific ratio. Means if one install disc in rear without balancing the front brakes, rear will lock yearly.
Ae80 and ae90 have bigger front disc ae101 GT has bigger rear disc.

[Hassan1991]

Actually homework should be done before upgrading the complete brakes otherwise your ended up having slips.
Apka case ma it will work fine as Proportional valve is made for front disc and rear drums. You just upgraded front brakes....

[rockstar.mij]

Yes bro...but someone told me that disc brakes can also be installed instead of rear drum brakes.
Will the handling be improved by doing so?

[pwuser147983858371]

Handling would not be improved just looks and handbrake might be bit better. But drums are good enough for this car.

[Hassan1991]

Bhai it's useless without corresponding Proportional valve.
If you want to install rear disc then you need ae82GT Proportional valve and rear discs. Or you can also use ae92GT proportional valve. Ab apko bhi pta hai inka valves milna asan thori haien.
Handling pe effect nae hota but it's a great upgrade as cars stops fast so you can go faster

[pwuser147983858371]

Brother most of the times you can get rear discs i have seen many AE90 and AE100 with them very less AE80 though but remember if you don’t have proper technique don’t do this as it can be dangerous. Corolla’s which came with standard 4 wheel disc had different master cylinder and boosters also the propotionating valve. Only by slamming rear disc setup ain’t worthy you’ll be locking up your brakes very often too. Same is case with 2003-2007 corolla xli gli 1.3 that car is 4 wheel disc but other parts like master cylinder booster valve aren’t capable of 4 wheel disc setup and car has high ground clearance which caused it to have worst brakes and brakes lock up at speeds more then 80km/h. But on other hand Corolla Altis 2005-2007 same shape never had any braking issues due to fact it had complete different braking system also had abs. Bigger rotors and calipers with better master cylinder.

[Hassan1991]

Me and my friend did great research on Proportional valve,master cylinder and disc sizes of corolla.
That's why said ae92GT valve will work.
Ae82GT came with 4 wheel disc brakes with different proportion valve brake booster and probably master cylinder compare to base model.
Your absolutely right and that's why nick name of that corolla is Khota
Ae100 came with both 2wheels disc and 4 wheels disc. In ae90 one can swap complete front and rear disc along with proportion valve and brakebooster of ae101. While in ae80 rear disc doesn't fit without much modification.
Locally Proportional valve is called 'T'
Weight is also a Big factor which people usually neglect.

@Hassan1991 bro ...yar how hot should be the car rims? In my case I feel it warm..but I feel urge to remove my hand after constantly keeping my hand touched with it..
