dodgy brake lights
The latest issue with my 70' beetle is that the brake lights only come on when i stand on the pedal, I bought a new switch to replace one of the old
ones but i can't get at it. the master cylinder is rotated a few degrees which points the switches towards the pan so there is no room to get a
spanner in there and turn it, can anyone who has replaced a switch before help with some advice ?
I have had a few near misses with my rear bumper on the ring road lately and i want to use the car as a daily runner.
Cheers,
Scott

The lights are only supposed to come on when you push the pedal, or is it excessive pressure you are applying before they come on?

How's your master cylinder been rotated a few degrees... they'll only go in one way !!!
Way I've done it in the past is to just take the RHS front wheel off and get access through the wheel arch... car safely on stands of course. An open
ended spanner of the right size should be all it takes.. 19mm I think ???
Be aware that you WILL need to bleed the brakes afterwards tho, so make sure you have suitable brake fluid, hose, a helper etc. on hand when you do
it.
Good luck !!!

Oh hey if you've got access to a multimeter you should also check that it really is the switch that's the problem... you said "switches" (as in
late model master cyl)... I'd have thought it'd be unusual to have 'em both fail, so could be a wiring issue somewhere.

I had the wiring checked by an auto electrtician and it's all good, it can only be the switches which have corroded when the car was off the road for
a few years, The brakes work fine just the first inch or so of travel - until the pedal gives pressure - does not activate the lights.
I will get the wheel off and have another go at the weekend.
Thanks

Scott, the brake light switch is a pressure activated switch, the lights won't illuminate until you feel pressure in the system
