Is a flat-ended or tapered hydraulic hose better?
A flat-ended hydraulic hose connector is better than a tapered one.
A tapered one refers to the taper of the hose’s sealing surface.
Hydraulic hoses are high-pressure hose assemblies, specifically categorized as rubber type (braided, spiral), metal hose, and low-pressure PU hose.
Connectors include welded, compression fitting, and flared types, and are available in US, UK, and metric systems.
Hydraulic hoses connect the fuel pump and engine nozzles, supplying fuel and hydraulic fluid to the steering system to reduce steering resistance. Brake hoses connect the brake pump and brake pad supports. When the driver applies the brakes, the brake pump pressurizes the brake pads with brake fluid, causing the pads to compress the brake disc and decelerate the vehicle. Most cars now have a return line. When the fuel pump supplies fuel to the engine, it creates pressure. Excess fuel, besides being supplied normally through the fuel injectors, is also returned to the fuel tank via the return line. Of course, the carbon canister collects excess gasoline vapor and returns it to the fuel tank through the return line, thus relieving gasoline pressure and reducing fuel consumption.
How to disassemble a motorcycle hydraulic disc brake line assembly?
The brake caliper piston has escaped, and bleeding the fluid won’t help. Disconnect the connected brake line and remove the brake caliper. The piston should be rotated vertically and slowly, pushing inward. Generally, you can force it all the way down. Reinstall the brake line and bleed the air.
I suggest you go to a motorcycle repair shop to remove a small amount, as there is brake fluid inside. After disassembly, the fluid will leak. Even if you reinstall the brakes, it won’t help. You must add brake fluid back in.
It’s likely that air is not being expelled from the brake line or pump. After adding fluid, hold the brake lever without releasing it. Loosen the bleed screw on the pump until no air bubbles appear, then tighten it. At this point, release the brake lever, and then repeatedly hold and release the brake lever. The air bubbles will usually gradually come out from the bottom of the pump, sometimes it may take a long time…
Generally, after replacing new lines, the air in the lines should be bleeded. If there is no pressure on the brake lever, most of the air has not been purged because the air compression ratio is greater than the brake fluid compression ratio, resulting in weak braking. Additionally, there may be air in the upper and lower brake pumps, or the pumps may be faulty.
The brake pump operates on a hydraulic principle. When braking, the brake lever or brake pedal pushes the piston on the brake pump, forcing brake fluid into the oil line and pumping it down. Like a jack, a small amount of force is sufficient to achieve braking. After releasing the brake, this force disappears, and the brake fluid can flow back to the brake pump. At this time, the pressure on the lower pump piston disappears, and the brakes…
