Good morning,
My good people of nairaland..hope u all had a great weekend..
Please,i am in need of an automobile expert counsel .
I was having issues with my 2006 corolla ABS box..i noticed it vibrates on my brake pedal when ever I apply brake especially when i am on speed.

So I ordered for the ABS from onicha ..After fixing it the vibration on pedal persisted. I was advised to bring the car to onicha to try other ABS..
THE ISSUE NOW!!!
Getting to onicha, I had the ABS replaced ..but now the brake pedal has gone totally down when u apply it..the old one was replaced still desame problem.. they bleed and bleed ,wasted 8 hydraulic yet the problem persisted.

there is high fluid pressure on the left front wheel (drivers side)
And very low fluid pressure on passenger front right wheel .
Back right wheel there is high fluid pressure
Back left wheel There is low fluid pressure

mechanic pointed to the master brake cylinder which was rekitted and certified ok..it pressure is visible high from the master brake cylinder but low on two aforementioned wheels..
The mechanics are still pointing to the master brake cylinder.even when the sellers inspected and said there is nothing wrong with the master cylinder.
Unfortunately the corolla came with avensis 14 - bolt master brake cylinder..
The once at onicha are all 10 bolt master brake cylinders.

The mechanic advised i purchase 10 bolt master brake cylinder and construct it.
What could be the problem now?
My car is still at Onicha..grounded.
I need professional advice ..
Pls help a brother out.

Change the brake pads and master brake. This should help since you have replaced the ABS

I didn't even think you should have gone this far even if I have limited knowledge of car repairs.

What I think you ought to have done first was to replace the brake pads.

If the issue was that serious, like making weird noise when reversing, then you can change the disk itself.

Check the brake disc. The issue is from there

The issue now id that the pedal is dropping..no brake at all

Vibration when brake is applied has to do with worn out brake discs and solution is to replace brake disc and then put fresh brake pads along. Why going to touch ABS I no understand.

Anyway, start from scratch and check your brake lines for rupture, then replace with exactly what was removed

Wahala to who go buy fairly used car wey get askident,wey mechanic panelbeat come repaint am.The exterior surface go look new to the buyer but the engine don pafuka.
Oga sell the car.That car go empty your bank account.

first issue after two years usage bro..mind u i imported it myself .. na me go find troubles..it wasn't that bad..

I think you should have checked your rotors and brake pads first. I faced a similar issue earlier this year, I didn't want to wait to get the oem rotors, so I machined the rotors and got new brake pads. You went overboard if you ask me, you should have started with a simple fix first. Where you getting any lights relating to that system on the dash? I will only do what you did if I had scanned the car and gotten an error code saying the ABS control module was faulty.

ALWAYS scan you car first before taking a mechanic's advice on such delicate systems, even doctors order for tests before giving a diagnosis.

Change your sabo... Is d cause. I once face something like that..d brake pedal always go floor when place foot... I change everything yet d same problem until I change sabo and set the bolt to stop d air. All went well...

Return back ur abs and change brake rotor and pads
