Aluma Lite brake issues

Two questions:

First, im having issues with the brake lights. I believe they are only intermittently working. The blubs appear fine but i will change them to be sure. All other lights work fine. Any insight? I still have to check the brake pedal switch, but any info would be helpful.

Second, the brake warning light comes on the dash occasionally. The brakes are working fine (the pedal travel is pretty long though) and i feel no changes when the light is on, but im assuming this might be the signs of a failing master cylinder. Thoughts?

Thanks in advance.

Check fluid.Google vid how to bleed brakes. Might want to get a brake bleed tool from harbor freight/amazon and start at rears to get any air out. First soak bleeders for days with Kano Kriol bang around bleeder small hammer ,the shocks can loosen rust and bleeders threads. You can tap the bleeders some as well carefully not to mash them up. . Add some new fluid as you go until what you draw looks clean. You don't want to empty reservoir and get air in master. Brake fluid does degrade from heat and time. New fluid is good. Wear nitrile gloves brake fluid is nasty.
Pump brakes search for leaks.If you still have brake light probably master is getting weak.

Ok cool. Im a mechanic so i have my tricks for bleeding brakes. Good call on the Kano Kriol though.

Where IS the master cylinder in these things. Under the dog house?

Hi ! Welcome to IRV2! We're sure glad you joined the gang!

I'm far from being a mechanic so can't help with that. Just noticed you are kinda new on IRV2 and wanted to say hello! Have fun and keep her between the ditches!

Good luck, happy trails, and God bless!

So the brake pedal switch appears to be working, but admittedly its hard to tell without the lights working. Any tips here?

Thanks again in advance.

Most likely a ground issue. Take a piece of wire and make sure it is grounded, then touch it on the side of light socket while someone is steping on the brake pedal. Or use a good test light or voltmeter to se if you have 12v at the socket using other ground source then the socket ground.

Wow, how did we get to bleeding the brakes ,,, The OP said he has an intermittent brake light issue and also a brake light warning light on the dash.
Testing the brake light switch is a definite step. The warning light coming on occasionally is a separate issue. Fluid level is monitored with a sensor, make sure the fluid level is normal. Worn brake lining can cause low fluid level and trip the sensor. All the fluid is down at the wheels making the level low.
Look for a brake fluid leak, you got a leak you know it quickly, ya don't bleed brakes unless you opened the system, Or if the master cylinder sucked air because the bowl went empty. OP said his pedal has a long stroke ,could be a adjustment needed if there's drum brakes out of adjustment. The warning light can come on if the master cylinder has coast down. Test by applying 'light' steady pedal pressure and see if the pedal coast's down to the floor. . At the bottom of the stroke the warning light may light. Internal leak, fluid passing by the plunger seals.

I dont believe it is a fluid issue (although i would still like the check. Where is the MC?)...so i agree that i wouldnt even think about bleeding. The pedal travel is long, but it stop consistently and reliably. Im not worried about brake performance.

I now see that brake warning light is related to the e-brake. Im sure thats just a bad switch as it only accasionally comes on while driving. Usually goes off quickly No rhyme or reason. Doesnt seem to be connected to actually braking.

I think i have solved the issue with the brake lights but ill have to confirm once my helper returns. Hard to see the brake lights from the drivers seat lol. I believe it was a switch issue. When i got under there it was loose in its mounting. I tightened everything up and will check switch alignment again when my helper returns.

If that doesnt fix it, ill test the connections with my meter.

Thanks again.

Brake issue was just the switch. Easy.

Where is the master cylinder? I checked under the hood and I don’t want to open the doghouse while it’s hot if I don’t have to.
