m101a2 brake fluid cap removal

[Contactmo]

I just got a m101a2 and can't get the brake fluid cap off. It appears as if someone took a pair of pliars or channel locks to it trying to get it off without success. Could anyone provide a pic of what it looks like when the lid comes off? Does it screw off or pop straight off?

Thanks.

definitely screws off

Thanks for the quick respons. Tomorrow this cap is coming off one way or another and hopefully it doesn't look like yours inside!

I kinda think it's not supposed to look like that on the inside.

HA. It made the decision to remove the surge brake assembly that much easier. Only a few drops of fluid were in the entire system. Yes, the cap just screws off.

Here is what I did. Remove master cylinder. Blow out loose scale with gentle air (cover your eyes). Also take a small screwdriver and scrape loose what scale you can. Then rinse with mineral spirits but don't pump it. Dump and rinse. You may have to rinse several times before youget clear clean mineral spirits out. Agitate mineral spiries with tongue depressor or something to get it good and clean. Once clean the fill again and pump to flush output. Pump till clear and then dump. Pump dry. Reinstall and fill with brake fluid. I use DOT 5 after I flush the enitre system. Use DOT 3, 4, or 5 - whatever floats your boat.

Sadly, if the cap is rusted on then the inside is probably rusted also.

True but if he got the cap off, mine looked nasty inside but cleaned up well.

You can always take it off and fill it with Evaporust and let sit over night. Rinse it out and it will look just fine.

Even cheaper, white vinegar 6 hours is enough then rinse well.

Have you done anything else besides wheels and tires?

Took a pipe wrench to it with some determination and she opened up. It's not so pretty inside . I'll clean out as instructed and hope for the best. Thanks!

Mounted a spare and added safety chains today.
Vin stamp and plate from DMV (home made trailer)
Flat 4 for lights installed.

Next up is paint wheels and trailer after I get brakes working.

That master cylinder is as dirty as an ice machine in a fast food restaurant.
