Question: How To Bleed Magura Brakes

Can you bleed Magura brakes with a Shimano bleed kit?

Shimano brakes use mineral oil as do Magura brakes, so there’s no fundamental incompatibility and you can use the same bleed kit providing the fittings work.

What oil do you use for Magura brakes?

All MAGURA brakes use low viscosity mineral oil (Royal Blood) as hydraulic medium.

Can you use mineral oil in Magura brakes?

Magura brakes use mineral oil brake fluid only. Never introduce DOT brake fluid into your Magura brake system. Using the wrong fluid will damage your brake’s internal seals and may result in brake failure or premature wear.

How do you bleed brakes by yourself?

How to Bleed Brake Fluid, One-Person Bleed Safety First. Park your vehicle on a flat, dry surface and install wheel chocks. Remove the old brake fluid. Add new brake fluid. Determine Which Wheel to Bleed. Locate the brake bleeder valve. Connect the vacuum pump. Open the bleeder valve. Close the brake bleeder valve and repeat.

Can I use Shimano mineral oil on Magura?

Should be fine, you can use oil that is not labelled for bicycle brakes too, as long as it is compatible with the seals. Viscosity does make a difference. Too high viscosity gives brakes that are sluggish, but if you are using bicycle brake specific mineral oil you don’t need to worry about that.

Can you use DOT 4 instead of mineral oil?

No, mineral oil and DOT brake fluid are different and are NOT compatible.

What can you use instead of mineral oil for brakes?

Alternatives for mineral brake fluid / oil (in a pinch) Fork cartridge oil (the lighter (more viscous) variant) Total / Castrol LHM Plus Fluid ( I believe it’s power steering fluid).

Why are my bike brakes still spongy after bleeding?

If air gets into the brake lines, it can prevent brake fluid from flowing properly, causing the brake pedal to feel spongy or soft. If the brakes are soft or spongy, this is a good time to change or flush the brake fluid. Flushing the brake fluid, commonly called bleeding the brakes, gets rid of the air.

Why are my bike brakes spongy after bleeding?

A spongy brake lever, or a brake lever which has to be pulled a long way before you feel the brake start to work, is a sure sign of air trapped in the brake system. Some brakes can be more troublesome to bleed than others. Even after multiple bleeds air can remain trapped inside the caliper.

Can I mix different brands of mineral oil?

Mixing different mineral oils is generally low risk due to the similarity of the chemical hydrocarbon structure of all base oils. We still advise mixing our lubricant with the minimum amount of competitor oils.

How do you bleed Magura Julie?

Squeeze the lever blade, hold pressure and check hose connections and the reservoir cover for eventual leaks. Squeeze the lever blade several times (pump) to push the pads to their proper position until the lever feel becomes very firm. If you cannot realize this, bleed the brake (see page 15 onwards).

Can you mix mineral oils?

Mineral, Semi Synthetic and Synthetic oils can all be mixed together, although this is not recommended. The reason this is not recommended is that during the blending process, various and different additive packs are added to the base oil to achieve various oil specifications for different intended applications.

Do you have to bleed new MTB brakes?

All new brakes come with a factory bleed. Sometimes this factory bleed really sucks. New brake cables usually require some trimming and so a bleed will be required if your cables need to be cut to fit properly.

What is in mineral oil?

Most often, mineral oil is a liquid by-product of refining crude oil to make gasoline and other petroleum products. This type of mineral oil is a transparent, colorless oil, composed mainly of alkanes and cycloalkanes, related to petroleum jelly.

What do Magura brakes feel like?

Both brakes use the same tiny twin-cylinder, single-piece forged caliper that’s also available in a flat-mount version. 2 rotor with power levels comparable to most single pot XC/Trail brakes. Modulation and feel are typically Magura, with a hard bite and then softer stroke as the body flexes.

How do you get air out of your brakes without bleeding?

How to Get the Air Out of Brake Lines Step 1: Find the bleeder. A screw and hose are located under the brake system and will be used to bleed the brake fluid. Step 2: Use the plastic hose. Step 3: Using the braking system. Step 4: Refilling the system. Step 5: Repeat the procedure. Step 6: Check the brakes.

What is the best way to bleed brakes?

The correct sequence for bleeding car brakes is to open the bleed valve, expel the brake fluid using gravity, pressure, or vacuum, fill the system and then close the bleed valve. How do I get the air out of brake lines? Bleed the brake lines and refill them to get the air out of the system.

Do you bleed brakes with car on or off?

6 Answers. If what you meant was bleeding the brakes at the calipers to remove air from the system, you should bleed the brakes with the car off. While ‘pump’ was the wrong word to use, the brake booster runs off the engine vacuum (it’s a large diaphragm that multiplies brake force), and this should not be active.

Why does Shimano use mineral oil?

One benefit of mineral oil over DOT fluid is that it is non-toxic. If you happen to spill a little on your bike while working on it, the mineral oil is less likely to cause any damage to other parts. This is one of the reasons Shimano mentions that they have chosen to use mineral oil.

Does mineral oil go bad?

The best part of food-grade mineral oil is that it has no expiration date and can easily last for a long time. Applying the oil at least a week before using the specific surface comes highly recommended.

Can you use regular mineral oil in Shimano brakes?

Broadly speaking, hydraulic disc brakes designed for bicycles will use either a mineral oil fluid, or an automotive DOT fluid. Genuine Shimano Mineral Oil is the only fluid compatible with Shimano brakes.
