@xulfiqar is there any way to alter the proportional valve of front disc - rear drum to make it for front disc - rear disc ? Because i find no visual difference in them and its not possible to differentiate them. Valves are available enough but no clue how to find out if its for front disc and rear disc specs

This Is Why I Always Recommended To Get Complete Set Along With Propotional Valves When Converting To Rear Discs...W.o Getting Complete Package..Rear Disc Conversion Is Worst Than Drum Type...!

You are absolutely right farrukh i had a ride in 8y with rear drums its brake was better then mine ! Problem is complete setup cannot be obtained since everything comes in parts and even if they provide you complete setup there is no way to know if the proportional valve is for drum or discs ! Do u have any idea how to differ them ?

@xulfiqar bhai, @capsat bhai, @syncview bhai. Is there any thing like resonator in engine? If it present what is the purpose of it?

resonator is inverse of exhaust silencer , as the word is self explanatory " Resonate " its like amplifying the NOISE of exhaust, in desi way .. it is ' saylancer nikal dai fir awaz sun zara patakha bhi bolay ga '

.

there is also a resonator in the intake, without it the intake roars when the throttle opens (which young kids like for some reason)

the brake master cylinder for the GT model of AE82, the classic AE86 and the TE72 are the same except the TE72 has a cast iron one, the prop valve work the same in all, there is no huge difference per se except the shapes.

Im highly inclined towards the brake master cylinder being faulty here as you are complaining of weak response with gradual pressure application from your foot. (this almost always is an internal leak in the master cylinder)

I would suggest you remove it, remove the cups and carefully inspect the bore for any oddities - even a slight scratch can cause this. if none are found then reassemble it with a touch of silicone grease on the rubber parts before inserting in the bore.

before mounting to the car, make some plugs for the pressure ports on the master cylinder and bleed it out the fiat way - plug the ports, fill up brake fluid, pump the pushrod to remove air. hold the pushrod in with pressure. if the pushrod sinks in - you have confirmed the culprit is the master cylinder.

What was the bore size of the ae82 GT master cylinder ? Because i am using 15/16 now and also i changed the master cylinder the pedal now doesn't sink and response is perfect on low foot pressure brakes but if i apply the brake rapidly and with full force the rear discs looks like they don't even are engaged ! If you still suggest ill open the master cylinder and inspect it the way you said i also have silicone grease with me so no issue ! Also do you suggest i take out the prop valve from a GT ae101 cut ? Try that if it improves the rear hold in full foot pressure brake

Aoa , Xulfiqar sb ,i have 2 questions for now ,there may be many more to come as i am planing on a restoration project .

1) what is engine oil capacity of a 2L (up model according to mechanic) ,or how much oil to put in on oil change with filter change.

2) are injector nozzles of kia sportage diesel available ? if yes what number are they or what to ask for with out mentioning kia ? thanks and regards

Zulfiqar sahib, i got 'p0401 egr function faulty' code on passo 2007. Do you have any idea how to check 6 pin egr valve?
Here in mansehra the mechanics even don't know what egr stands for.

@Xulfiqar
I have recently got my 82 corolla 4K engine overhauled, 3000km now, which oil grade i should be using?

@xulfiqar, I hope you're doing good.

My 2007 Honda Civic Hybrid's electric steering has become hard. Since the past 2-3 months, the car's steering wheel has become harder and harder to turn. The steering feels heavy and makes a 'wooh wooh' sound when turned which it didn't make before. The sound sometimes becomes very loud. Occasionally, there is a 'krr krr' sound while turning.

Only the front suspension boots have been replaced with new ones.
I'm using Continental Premium Contact tires on the car which have only been driven 20,000KMs. I put 35 PSI in the tires (this should reduce the hardness of the steering, in my opinion).

I've had the car hooked up to a OBD-II scanner to check for any fault codes regarding the electric power steering pump but there weren't any errors. The car doesn't give any errors on the odometer display either. The car starts normally and the steering wheel unlocks normally as well.

On the other hand, my 2013 (PKDM) Civic's steering wheel is very light and easy to turn. It also has electric power steering.

What do you suggest would be the culprit here?

Would really appreciate your response.

[capsat]

visit workshop having a scanner, get it scanned. It seems that the electric steering motor is about to die. Please recall if the problem started after service and engine bay shower as in dolphin taking a bath. ... ! ...

a. Toyota 2L diesel engine variants will take between, 5.5 to 6.2 liters of engine oil, add another 750 ml when changing oil filter.

b. model year of KIA sportage & engine capacity . ?? - KIA uses Mazda technology and if you ask for MAZDA diesel engine parts you get T3500 stuff in PK

2. Which one to take ou

t, one or both. If one then which one?
Please

@mani2263 you can not disconnect the ABS just by removing a fuse / relay. The ABS signal input is looped to ECU for safety reasons. Exercise caution ABS is for your own safety as well as for other people on road. Vehicle stability & your life is linked to it. @syncview

I have never had anyone spray water into the car's engine bay. The car is washed regularly but the engine bay usually remains dry. It is a hybrid so I've never had anyone bring water near its electrics.

The car did not display any errors when the scanner was plugged in nor is it giving any errors on the odometer.
I suppose its part of general wear and tear? The car is driven 130,000KMs and has been maintained according to the maintenance schedule in the book.

But dear i am having trouble with abs. New genuine pads installed, rotor faced. But brakes produce strange noise and the braking distance is too large. Any suggestion?
