Amazon: Brake Light Switch

[Splinelube]

Could someone tell me if the brake light switch - later model from year 1966 - is removed from the interior of the car or from the engine compartment? Thanks in advance.

as I recall the transition from hydraulic pressure sensing switch locate on a brass brake line junction block in the engine bay, possibly on the firewall, to a mechanical switch under the dash triggered by the brake pedal was 66/67.

have a look in both places and see what you have, if you can't determine, post a few pics.

C1800 has it right...changeover from earlier hydraulically activated (located at hyd brake distribution block on firewall behind engine) to later mechanically activated (located in pedal box of footwell) BLSW took place in 66-67' (market dependent).

I have been on a campaign to get owners with hyd type to change over to the later type for reliability and other advantages, since I recognized the safety disadvantages of the hyd switches years ago. See: http://www.sw-em.com/safety_bulletin_4.htm

Thanks to C1800 and Ron for your replies. Problem solved, was oil/grease buildup on both electrical contacts. No disassembly required.

Sl;

Congrats on locating and repairing, and thanks for following up with a report of findings.

Be aware...if "oil/grease buildup on both electrical contacts" is enough to prevent electrical contact, the spring preload of push-on terminal (which should be present!) must not have been very good, because by design, pushing on terminals should cut through oxidation and surface contamination to allow contact of clean metal surfaces. This means after cleaning terminals of switch, you may want to (at the very least) squeeze terminals to restore some preload, and (at the very most) replace crimps with new! ...and of course: Apply ACZP!

Finally, you may have restored Brake Light function, but you haven't removed any of the known weaknesses. Please keep upgrading in mind as a future safety and reliability improving option!

On your brake switch upgrade do you supply a bracket suitable for a RHD car?
