When I press the brakes i hear a 'ppshhh' noise.
I dont think its normal.. The level of fluid was real low
(and pedal travel was deep) so I added fluid.. but after the brake
pedal was still low.. and that noise is constant..
The fluid reservoir isnt clear either.. it seems like there's
a build up of dust stuck inside .
I guess I should empty it.. clean it.. then bleed the system..
What should I do ?

Thx for ur responses

p.s how are 3rd gens supposed to brake with stock parts?

 

Sounds like your master cylinder leaks, and the fluid has killed the booster.

So before you bother with any cleaning and bleeding, replace the booster & MC; they are available as an assembly.

Most of these cars have pretty good brakes, except that they kind of fade alot with hard hig-speed usage.
