Are all Shimano brake hoses the same?

Brake hoses – Shimano essentially use two hose designs. They both have the same external diameter, but the internal on the higher end hose is narrower. As the surrounding material is steel-reinforced, this makes the hose stiffer on the narrower hose. The cheaper hose is code BH59, and the stiffer hose is BH90.

Do you need to bleed Shimano brakes after shortening hose?

You don’t need to do a full bleed though. Just cut the hose, fit the barb and olive, and tighten everything up, then take the top bleed bolt out, fit the bleed funnel (or bodge it with an open syringe or something), top up with mineral oil and pull the lever and tap the hose a few times to dislodge any bubbles.

What is the difference between BH90 and BH59?
