Obmade you've got your answers. You're now guided I'll say.

I already know disc has advantage over drum in heat transfer, but also improvement has been made greatly in brake system that even a drum brake on all four tyres would be effective.
in a FWD configuration majority of brake power is needed in the front that is where power nd weight I concentrated, so disc is used infront while the drum at the rear provides additional assistance.

the only corolla model fitted with disc at both ends is the XRS same for matrix and pontiac with the addition of the AWD to the matrix/pontiac vibe, this configuration comes with a 2.4L engine against the 1.6 or 1.8L stock engine these configuration were meant to be performance car (I really don't see any much performance sha ).

is running disc at the rear ok? yes it is

will disc brakes at the rear give me an advantage? yes

is fixing disc at the rear better than drum? the gain in fixing disc against drum is negligible

why do majority corolla users replace drum with disc? for aesthetic purposes as the disc with matching alloy rim gives the tires a unique look.

which one last longer, disc or drum? drum brakes last longer due to their protective design enclosure while disc brakes need constant checks and change due to exposure to sand and stones.

nurey:


[s]your mechanic is only interested in fleecing you, there is no need to run disc brake at the rear of your car, is toyota engineers stupid to install drum brakes in 90% of corolla at the rear.

You can install disc brake at the rear if you wish, but the drum brakes fixed therein gets the job done perfectly. installing disc is just going the extra mile[/s] or wait, did you qualify for grand prix?

Why Disc Brakes are Preferred to Drum Brakes

nurey:


Tell your mechanic that I nurey is asking him when he carried out the research trail, what was his inference and outcome, also I need a hard copy and soft copy of the project work and results.

a little online research of drum brakes vs disc brakes will enlighten you which is better. Most who change the rear to disc is for aesthetics purposes.

nurey:


I hope you are not doing it for the aesthetics

nurey:


if the car in question has a trim with brake discs, you have my go ahead, you just buy the necessary parts nd swap.

drums aren't bad, except you buy low quality shoe and dip them regularly in water especially when they are extremely hot

feelme3:


Abeg, which area is the mech that corrected yours? I dey go revert mine. Problem is the Kazeem that removed the thermostat probably threw it away.

mayor2013:


You are covered as long as ride doesn't overheat

feelme3:


Nice testimony bro. But have you used your AC for extended period and never experienced overheating since the revert?

Namzy:
Thermostat only opens to allow cool water at a particular temp and will open and close when coolant is hot and cold so the disadvantage of running your fan directly is increased wear and tear of fan engines and maybe a slight rise in engine performance to accommodate fan running always

timifakay:


Don't be surprised, if you interview the person who reversed the connection, did so just because he needs money and sees you as stubborn, so he wants you to learn your lesson the hard way.
Congrats and stay safe sir.

luvinhubby:


Some hired assassins abound, wearing mechanic overall and clutching bags of tools.

erico2k2:

Thank God you experienced it 1st hand, if you tell most guys they will think you are talking BS. Africa is Hot indeed!

thebigkendo:


Hmmmmm bros your car go overheat oh. Direct fan and thermostat delete is for Naija temperature

Alvin007:


O2(oxygen) sensor codes vary...but the best way to ascertain the presence or absence of a catalyst converter is mostly through physical inspection..coz the p0420 catalyst code might not pop up until all other pressing codes are dealt with.

Alvin007:


My brother, these codes are camshaft and transmission(solenoid) codes. And yes, ‘indomie’ is the same as ‘catalyst’ instant noddles.

Alvin007:


Which of the indomie?...the instant noddles or the hungry man size?
What codes did you get?
