Brake Lights Staying On

Brake lights staying on !!

 

Hi all

Just noticed my brake lights and wing light are stying on . Took it for a short drive then put it on stands to see if it brakes ok .It does. Checked all the fuses all fine . Took the battery off.

 

Any suggestion / ideas would be much appreciated

Cheers

Bruce

They are controlled by a small, adjustable switch at the brake pedal.

First unplug the switch at the pedal and make sure the light goes off.  Assuming it does, push the switch a few times and see if it frees up, and if not it can be adjusted a little.  Otherwise it may just have failed and need replacing.

Yes it was the switch thank you.

Also found rubber/plastic button like bits on carpet which, I assume hits the switch ???

Seen the whole brake switch on Super cheap Auto would they fit ? or just find the rubbery end bit?

Thanks

I'm not near the car to check, but this is the service manual page for it

It looks like a similar setup to my navara where the rubber stopper disintegrated a few years back leaving nothing for the switch to turn off against. Pretty sure I picked up the part at nissan for a few bucks after my dodgy fix failed again.

This has happened to me in every import I've owned.

When that rubber piece brakes, I just super glue a five cent piece over the ensuing hole. Otherwise that switch doesn't get depressed when you let the brake off.

gotta love SAU!

My brake lights were on when I came home yesterday - figured it was most likely the switch, but did a search on SAU and bingo!

Even found the bits on the carpet, but wow it's tight under there :( - a quick look last night and another this morning, I was able to push the button in to prove the fault, but didn't have time to try an maneuver a 5c piece or similar in to activate the switch, or disconnect the connector...so the brake lights stayed on - got home tonight and the bulbs are blown - I should have disconnected them at the tail lights in the boot!

Not surprising in hindsight - cautionary tale - of course brake lights won't cop being on for 24hrs - they burn bright when required but aren't designed to stay on. At the time I was more concerned with flattening the battery, so had the battery charger on.

No biggy, bulbs are cheap...

I'm more concerned with the contortionist activity required under the dash to fix the switch - likely I'll have to remove the driver's seat to give me more room...

The glued 5c piece option sounds dodgy, but actually looks the best solution compared to swapping the switch assembly including disconnecting/reconnecting the connector...getting to it is tricky - admittedly I was holding a torch in one hand, so a fixed light source and 2 hands would help.

Is the rubber grommet piece available as a spare part - preferably without buying the whole switch? Pushing a new grommet in looks even easier than the glued 5c piece (not that anything is easy under the dash :( )

I'm wary of doing any mods to the braking system (or in this case the brake light system) - am I being too paranoid or appropriately cautious?

The car is not a daily and can stay off the road for a bit.

cheers

thanks goes to @Duncan for the diagram so I could get the clearance right when re-installing the switch, and @Dose Pipe Sutututu and @duffmansbrew for where to get the replacement bit ?

Biatch of a job under there - removing the switch makes it "easier".

I used a smidge of silicon grease on the hole to help the rubber bit slip in, and a flat blade screwdriver for a bit of leverage - it doesn't need force, it's just in an awkward spot.

Thanks again SAU!

 

cheers

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
