Question about 1995 Toyota 4Runner

1 Answer

When push brakes you have to push really hard to make them go in then the truck barely stops. Replaced the MC and bled the brakes now every time push brakes truck acts like its going to die. Brake light still on and brakes doing same thing.

    did you check the seal when you renewed the m/c, at the booster,could be letting in air to the vaccuum side.disc rotors probably need machining,pads renewing,m/cylinder needs bleeding properly.bleed furtherist away from m/c,slowly,two people,plastic pipe on the nipple,into a bottle[do not reuse] and pump through till no more bubbles.

    pretty sure when bleeding we did it wrong. but when pressing the brakes the truck acts like it wants to die??? this truck is really emptying the pocket book....just had to change radiator about a month ago.

Sounds like you will have to bleed your brakes again, but thats not the problem og hard brake peddle, need to check your power brake booster, sit right in back of master cylinder, check make sure it has vacum going to it, also to test it with engine off, press on brake peddle three time, then state engine with foot on peddle, peddle should go down a few inches, also with engine of peddle should feel soft for three pumps, if you have none of this , power brake booster is bad.

1984 Honda Accord Brake pedal sunk to the floor and had to push extra hard to stop. Replaced master cylinder and bled brakes but right front had no fluid or air coming though the lines. So I replaced...


The problem is in the master cylinder. The MC is in effect two cylinders in one, one cylinder for the front brakes and one for the rear (one in front of the other). When the MC gets a bit long in the tooth pressure from one cylinder can leak past it's seal into the other cylinder or into the reseviour. The MC is leaking internally, but not externally, so you see no signs of leakage and don't lose any fluid as leaked fluid ends up back in the reseviour. Sometimes the symptom will be evident and other times not, on my car the pedal tends to sink sometimes on hot days but is always firm on cooler days(?). It really is something that does need to be addressed urgently as a matter of safety, because pressure is leaking from one cylinder the pressure in that cylinder won't be high enough. This will affect front to rear brake bias which can have a substantial adverse affect on braking performance, and may cause premature brake lock up at either the front or rear (not sure which end), which could cause loss of control (i.e. massive understeer or oversteer under brakes). $700 does sound at least a bit steep to supply and fit a new MC, and bleed the brakes. Here in Australia new Accord MCs are around AUD$180 or so. The pedal should be quite firm with little free play with a braking system in good condition, if yours typically isn't (before you had that sinking feeling) then the brakes probably need attention (bleeding most likely, but could also be a soft rubber hose, causing the hose to bulge under pressure, not good as it may burst).

The problem here is air in the ABS system, you must get the ABS hydraulic control unit bled, this can't be done with a special tool that holds open the poppet valves to each wheel so the air can be completely bled out. You must have the brakes bled at a shop OR the dealer that has this tool or its equivalent. There is no way around using the bleeding tool on this ABS system. I get this question over and over on FixYa.

Bleed right rear,left rear, right front, left front in that order to be sure of good bleed but the brake booster makes it easy to push pedal. Make sure of no leaks from master cylinder. Otherwise brake hoses being soft will also hurt baking quickly.
