PEDAL STOP LIGHT SWITCH 406

    I am having problems with the stop lamp switch on my 406 not always
    switching off when the pedal is released. The problems seem to be due to the
    pedal not returning to its stop under return spring pressure. This car uses
    a torsion shaft between the driver and passenger side. Where is the return
    spring located and how do you get at it. If you lift the pedal by hand the
    switch works OK. The Haynes manual says that the steering column has to be
    removed to replace or adjust the switch shortly not. It also mentions a
    special Peugeot tool is required. What is this and can it be made.

    i dont think the problem is the pedal not returning fully, it has to have a
    small amount of reserve travel upwards so dont attempt to modify it so it
    stops all the way at the top.
    the problem will be the switch, perhaps the bracket which holds it may be
    slightly bent away from the pedal, if you can get at it check the clearance
    between the switch and the pedal.
    the switch may have also popped out of the bracket slightly,
    get on your back and take a look under there.

    I have had a look at the pedal cluster. With the pedal pressed down you can
    press the teat on the switch and this operates OK, on off as required. There
    is now slack in the mechanical part of the pedal linkage to the servo and
    master cylinder at 70K miles. First instinct is to adjust the switch
    position which is catered for as the switch is threaded for this purpose.
    However it is a Peugeot and the switch is located directly behind the
    steering column and cannot be adjusted without taking the steering column
    out which Haynes say requires a special tool. I do not fancy paying the
    local Peugeot dealer £100 to 200 to replace and adjust the switch. I have
    provided a temporary repair by sticking a small piece of ali on the pedal
    where the switch contacts the pedal. This has affected a cure. This explains
    why I have seen a number of Peugeots with their brake lights stuck on.

    Why is there no return spring on the pedal as is normal on most cars. Or is
    it located else where.
    Why was the car designed so that such an obvious adjustment cannot be
    carried out.

    I was under the impression that, as the brakes wear, more hydraulic fluid
    gets drawn into the system so that the pedal travel remains much the same.
    If any of the experts in the group see this perhaps they would comment
    please. TIA

    Your assumption is correct as far as the hydraulics are concerned. My
    problem is that there is now mechanical wear in the brake linkage which is
    causing the problem.

    first of all its french, so dont expect anything to be designed with regards
    to servicing or maintainence, the french just dont work that way, for every
    reasonably clever or ingenious idea the french come up with there are 50
    that just make you want to bang your head against the nearest wall.
    the pedal height should not change throughout the life of the brake linings,
    as you mention any wear will be compensated for by added fluid in the
    system, (except for rear drum brakes where the self adjusters dont work)
    but this will still not affect the idle height of the pedal, just means it
    will travel further before it bites.
