4Runner Brake Light

Filed under: Uncategorized — admin @ 5:16 am

In my ’90 4Runner the yellow "rear Anti-lock brake system" light comes on
after I travel about 5 miles, also my parking brake light always stays on
but some times it is real dim, and other times it is bright as if I had the
brake on.  That light always dims a little when I turn the parking brake
off.  I have plenty of fluid in my reserve, what is the problem?

Brian

PS    -    sometimes I notice that when I try to stop quickly, it seems like
I             can push the brake to the floor before anything happens.

  1. I have a ’90 4Runner that with parking brake light would always stay on.  I
    heard the the sensor in the brake fluid reserve was bad, so I disconnected
    it.  Now the parking brake light only comes on with the parking brake is on
    and this even fixed my broken cruse control.

    Why don’t you have the sensor replaced and fix the
    problem. As it is now you have 2 problems to fix, and
    more importantly, you have compromised your brake system
    and if you ever have a fluid loss you will not know it
    till its maybe too late. REPLACE THE SENSOR!!!

    good luck Pat S

    for one thing, it’s over $70 for the sensor.  next, the reservoir is so
    easy to spot whenever you open the hood, you’re either blind or lazy to
    not check your vehicle’s fluid levels in the first place.

    before i did the same thing to my 90 4runner, i checked with a few
    sources about what the consequences are.  and what everyone told me is
    that the sensor just tells me the fluid is low.  no impact on braking
    performance at all.

    then for about half a year, i checked the fluid regularly, and for about
    a year, i don’t remember adding fluid at all…

    Hi there .. Oh I can see your point, But my point is say
    your driving 80 mph down I-5 and a component of your
    braking system pukes its guts out and no fluid…. at
    least you know, if you bypass and don’t know…well. Yea
    I’ll be the first one to stand in line for saving $70.00,
    but not at the expense that, that would be a BAD thing.
    Theres always MURPHYS LAW, and of course you know" Shit
    Happens" more often than not.

    Bye all and good luck Pat S.

    Actually this sensor isnt supposed to tell you just your fluid is low,
    its designed to tell your front brake pad lining is low!

    The design of this is you never add fluid, when it gets low, the front
    linings are worn way down! This is actually how this system is designed,
    and when you add fluid, it throws it all off!

    They didn’t tell you about the relationship to the cruise control!
    And, what about the danging wire under the hood?  Does it look good?
    You should REPLACE THE SENSOR!

    actually, the reason was because of the CC.  it refused to turn on.  i
    checked the fluid and it was fine.  but the light on the dash would
    blink and the CC would refuse to work.  then i unplugged it and it’s
    worked ever since…

  8. My ’88 did the same thing. Hardened valves according to the dealer(and Rick).
    Your repair is cheap, mine was $1,300.00.  I’d do it if you’re going to keep
    the car another couple of years, not much to keep it running good.

  9. This symptom can be worn valve guides..
    Do you really have to add oil between oil changes?.. I get a bit of smoke
    initally (178K miles) but change the oil every 3000 miles and never have to
    worry about adding oil.

    Same here.  No oil added needed.  So, no worry?  Is it going to shorten the
    life of anything?

  11. Same experience with an ’88. The valveseals are damaged, perhaps from
    overheating, Expensive job, if it passes smog test fine: oil is cheaper…
