My brake lights do not function and I am not sure why.

How do the brake lights actually work?

I assume they are not on a seperate fuse to the rest of the lights (and indicators?) which work..

Do they function with some sort of switch on the pedal? Or is it pressure related?

There is no visible switch/sensor on the pedal.

I didn't build the car and the wiring is untidy to say the least so it could simply be a loose connection. Is this likely?



I also bought EBC Greenstuff pads to fit M16 calipers (which I was assured I had by Stuart Taylor) but having inspected the calipers, they do not appear correct. The pads are almost square and quite small.
However, looking at the pad throught the side of the caliper, it appears to be 'normal looking' (longer, thinner and rounded on one side).
The calipers have Ford on them, the left has '30P' embossed on it and the right has '29P' I think there is one fairly large looking piston.
Any ideas what these are?
Is it actually the pad I am looking at throught the side (am I just looking at some sort of mountint the pad sits on) or do I really need to undo them to see the pad shape?

Any help much appreciated and would greatly aid my diagnosis.

I may have some EBC M16 pads available if Fisher don't accept them back.....

Brake lights would normally be on a separate fuse/circuit.

The light can be switched by a switch operated by the pedal or an inline pressure swich...both ways are common.

A loose conection and/or stuck switch are quite possible.

Sorry, can't help with rest.

If the brake lights are activated by a elctrical switch it's usually a plunger type switch at the top of the pedal, similar to a courtesy light switch but bigger with the plunger on the upper face of the pedal.

If it's a hydraulic switch it'll be plumbed in to the brake pipe, looks similar to a an engine temp sender with two spade connectors on the top.

M16 pads are rectangular and look like this

If you are struggling to find a match for your pads. I notice Halfords do a neat book with pictures and part no's of all stocked pads!

You could then xref this with the other book to find what car your calipers came off of.

FWIW,

Cheers all.

I have located the hydraulic switch in the brake lines and will be testing once my brakes are back together.

Having spoken to Fisher (who sold me the pads) they suspect my hubs/calipers are Sierra - which is nice, as the bloke who sold me it, having allegedly having it factory built, assured me it was escort rear, cortina front!
I have traced the outline of the pad and enclosed it with the old pads (which are on their way back) so they can confirm.

Will check out Halfords anyway though for piece of mind.
