It's for a non mercedes, mitsubishi montero.
after 3 new master cylinders the pedal still is spongy, pedal engages half way through and the stopping power is 35% of what it used to be before this problem occured. However, if i pump slightly and then press the brake pedal again it always is firm. Though the braking poewr still comes and goes even with this double pumping action. at times the brakes engage perfectly but subsequent brakings are back to less power.
the dealer service center and also the private shops i went to, bleed the system with the two person method. they donnt even use a bottle and pipe at the bleeding screws. they just squirt the fluid out.
with zillions of posts on shops having actual gadgets to bleed the m/c and the brake lines properly , I wanted to know if anyone knows of such specialty brake shops in central NJ area.
really would appreciate any input on the problem and also a recommendation for the shop.
thnx.
