Hello house,good evening.
So I have a 2017 Mitsubishi L200 2x4,the problems are
The brakes keep making hissing sound,like pumping air "shuuuuuuuu....." steadily when the car is on at the brake pedal,but when the brake pedal is pressed the noise stops and starts again when the brake is released.ABS light is on,
What could be the problem?I have bleed the brakes and the brakes work very well,just that annoying noise.
Mechanic say na master and sabo dey do am,but I no believe am because most of these guys are just guessing.
Secondly ,back axle dey make noise ,it just started today but the noise is still faint?
What can I do to stop this noise ?Or the only solution is to replace axle?I just gauge axle oil today too..
Please ideas are welcome,
Cc gurus;nurey,9icetoo,gazzuzz,laivwire and all other pros..

For the brake seek second opinion from a qualified technician.

For the axle sound, let the mechanic confirm the sound is really from the axle or other rear components then find out what it is an fix. Sound cannot be diagnosed online

For the hissing sound. Pull the vacuum hose that goes to the master cylinder and plug it. If the sound disappears, then you know your master cylinder has an issue (of course do not attempt to drive the car with the vacuum hose pulled).

For the rear noise.
First of all gauge the axle oil. Use the right fluid. Most probably a GL3 or GL5 trans axle fluid (please check the vehicle manual). Do not overfill.
If the noise persists, check and confirm bearings and hubs are okay.

If they are okay, then start saving for another axle.

Cheers.
