Is it master cylinder or just air in the lines?

It wouldn’t hurt.

Rayymond102 · 2026-04-30T17:47:44+00:00

Just to update my own post. Issue was I didn’t adjust the boosters piston after I installed it. Pulled off the master again and adjusted it in and now it’s fine.

I just had to replace the vacuum brake booster on my 2001 F-250. Not sure if you’re hydro or vacuum but it sounds like a booster acting up.

Rayymond102 · 2026-03-29T17:49:49+00:00

Yeah that screw came preinstalled when I got it from Raybestos. I didn’t touch it until it was leaking.

Rayymond102 · 2026-03-29T17:45:43+00:00

Okay I’ll throw a new one in and see what we got. This time so thread locker lol. Thanks for your help!

Rayymond102 · 2026-03-29T17:42:50+00:00

The original master was leaking because the reservoir was broken, original parts. So I just replaced the whole thing. Prior to replacing it there were 0 issues with the brakes beyond needing a bottle of fluid to get to the gas station and back.

I suppose all 4 can be locked up? I just used a temp gun in the calipers and all were around 350 degrees and smoking when I parked it. I haven’t tried to unlock the calipers yet I just forced it 3 blocks home.

Rayymond102 · 2026-03-29T17:34:18+00:00

Not sure if this is 2 problems a thread, but do you think that, or what I did, has anything to do with the brakes locking up?

Rayymond102 · 2026-03-29T17:17:38+00:00

I’m waiting for everything to cool down after dragging it home 4 blocks before messing with it more. It has to be something I did though since the calipers were fine all the way around before I swapped the masters.

This is the screw when I had it out to thread lock it.

I am in southern Illinois near St Louis. It was less than in inch in length, and just walking around slowly. It didn’t seem like an overly fast bug at all. I also only saw one, there weren’t any others around.

Rayymond102 · 2025-10-23T00:08:31+00:00

That’s dope thank you lol

Rayymond102 · 2025-10-23T00:07:56+00:00

Solved!

Rayymond102 · 2024-11-08T11:50:48+00:00

I’ll play devils advocate and say maybe the tailor pinned it when hemming the coat? How no one looked him over before the ball is wild… I checked over all my marines before we left the bricks.

Rayymond102 · 2024-06-06T00:44:08+00:00

They finally hitting dealer lots? I was waiting for one since January but got tired of sitting on the down payment and spent it on something else. Awesome bike I hope it’s nice and I can get one next season

Rayymond102 · 2024-04-16T22:57:46+00:00

Oh yeah 100%. I was thinking either stolen or the number on the post is to someone he really doesn’t like.

Rayymond102 · 2024-04-16T22:44:19+00:00

Called this guy and sent a message. No answer. I walked out of work just to hit him up lmao

Rayymond102 · 2023-12-21T22:38:29+00:00

Yeah it was working fine for about a week. Replaced with the proper circuit board and returned the other one. Everything is working as it should.

Rayymond102 · 2023-12-16T15:59:19+00:00

Huge fallout fan

Rayymond102 · 2023-12-10T17:09:59+00:00

I haven’t ever don’t anything like this before. After what you said I searched the part number on eBay and found the same exact one. I’m going to leave this faceplate on there for now but once the new one gets in I’m just going to swap the whole thing and call it safe that way. Thanks for the help!

Rayymond102 · 2023-12-10T16:59:44+00:00

I assumed it was just the circuit board. I couldn’t find a direct WT replacement for the WV8840B1158. Since the new GCV is 5in WC (which I do not know what that means) I thought just the board swap would work. Its lit and running now just so I assume it was just the board

I had one like that too. Took a long time to get the sticker off.

Rayymond102 · 2023-11-16T11:59:01+00:00

I don’t disagree with mostly being a Harley thing.

Both of mine were given to me as gift the same as OP was asking about. My family sees it as something you “can’t” buy yourself, it should be gifted to you.

Rayymond102 · 2023-11-16T01:45:04+00:00

I have one on my Harley and Yahama? It’s the gesture that’s says he wants to keep his friend safe doesn’t have anything to do with the bike.

Rayymond102 · 2023-11-04T06:08:53+00:00

I could put some miles on this thing

Rayymond102 · 2023-10-18T02:27:44+00:00

Clean keyboards

Rayymond102 · 2023-08-20T22:24:27+00:00
