Help troubleshoot brake wiring issues? 2010 TRD sport.

Hi,

I own a 2010 Tacoma TRD sport. Original owner. I was hoping one of you would be able to help me troubleshoot with some wiring issues. The wiring that connects to the brake fluid reservoir seems to be hanging on for dear life (circled in blue). I was hoping to easily replace? Does anyone have some advice? If there is a thread or some direction you could nudge me towards that would also help a lot. Thanks.

This is what I would do.

Cut the wires back to a section of good solid wire in both directions from the damage.

Strip the wire ends about 1/2 inch.

Add in a section of wire. Get the proper sized wire and then use a telegraph or western union splice, solder and heat shrink tubing.

Good advice for a temporary fix until you can get a replacement wire

 

A proper Telegraph splice that has been covered with heat shrink is a permanent repair especially if you use the heat shrink with glue inside for outside splices exposed to the elements.

Many people consider a butt splice a permanent repair and it doesn't have near the strength or integrity of a telegraph splice.

But to each their own...

 

Hey Jimmyh. Thanks for the tips and the reference. Is there any danger in making the splice too long? I was gonna cut a bit further back on one of the wires to bring it into the hardware shop. Just to match wire gauge.

 

Do you happen to know the replacement wire part number? I am assuming by replacement, you mean the harness with wires?

 

This is not necessary. Do as JimmyH has suggested. Get like 14 gauge wire, solder , and heat shrink. You can make it a little longer if you like but there's no need to replace the whole harness with an OEM replacement. Heck, it's been working being in it's current condition so any repair would be a massive improvement.

 

Thanks Wattapunk. Yeah, surprised it's been working too. Or at least I would assume so, as I have never seen a brake warning show up. Or maybe that is a sign it's not working, lol.

Anyways, I guess I would still like to see the cost of a harness. Might be more cost efficient. Either way, I at lease have a plan.

 

This is what I would do in the meantime. Strip back that frayed section, hand twist the connection, and wrap with electrical tape.

 

No not at all. I would recommend using the heat shrink with the glue inside to seal the solder joints
