Post by: camineet on April 17, 2025, 05:30:16 PM
Hi guys, would you take a look at this weak brakes problem I've found after my recent install?

Forgot to mention/admit that I used this mineral oil instead of Ltwoo official

This appears to be user error. There are details in the written Ltwoo instructions that aren't in the video about a push pull procedure. I did it and pulled out huge amounts of air. Haven't tested the bike on road yet, but I thought I'd report back and probably close this thread.

All the mineral oils are equivalent (not equal) but compatible.

You can mix shimano with magura with any problem, so the issue is not on the oil.

Can u describe the problem?

I can suggest you to follow this video, it's very well made and must be followed every step.
Consider that the Hope 4 piston are a real PITA to bleed...

Hi all. This issue was resolved fully with a LBS bedding using the smart bedding machine they have for $40. Money well spent. I'll not try finalizing a brake install myself again. I even tried bedding the brakes myself and got zero improvement. Got the bike back from the shop this morning and the brakes are very nice.

Glad to hear, do you know what "magic" the LBS applied? Only bedding in the brake pads or something in the bleeding procedure?

Really not sure what OPs problem was. I remember an incident right after I first installed my eGR. I was not used to fully hydraulic disc brakes. I was riding around town and my pinky carelessly touched my brake lever and it almost sent me over the bars. That is not a joke. I nearly tumbled ass-over-ankles in the middle of my downtown. eGR brakes are A-OK by me, lol.
