Hydraulic brakes feel their best when the lever is firm, the bite point is consistent and there is no spongy travel. A proper bleed can restore that feel, but the bleed kit and fluid must match the brake system on your bike.
Bleedkit.com makes brake-specific kits for home mechanics, while Park Tool offers comprehensive workshop-quality kits covering several brake brands. The right choice depends on your brake model, fluid type and how many different bikes you intend to service.
Start with the Brake Fluid
This is the most important part of choosing a bleed kit. Never put mineral oil into a DOT brake or DOT fluid into a mineral-oil brake. The fluids are chemically different and must not be mixed in the brake system or in your service tools.
- Shimano: Mineral oil
- Magura: Mineral oil
- Tektro and TRP: Usually mineral oil, but confirm the exact model
- SRAM DB8 and Maven: Mineral oil
- SRAM Code, Guide, G2 and many Level models: DOT fluid
- Hope, Hayes and many Formula models: DOT fluid, but confirm the exact model
Check the marking on the brake lever, the manufacturer’s service information or the individual product listing before ordering. Do not choose a kit from the brake brand alone because some manufacturers use more than one fluid system.
Shop Brake and Suspension Fluid
Bleedkit.com Basic Kits
A Bleedkit.com Basic kit is a sensible choice for someone maintaining one bike with a clearly identified brake system. These kits normally include the essential syringes, hoses, fittings and bleed block required for the brake family named in the product description.
Choose a Basic kit when you know the exact brake model, already have the correct fluid and only expect to service that type of brake. It provides the necessary equipment without filling the toolbox with fittings you are unlikely to use.
Bleedkit.com Premium Kits
Premium kits add useful tools, adaptors, bleed blocks or replacement parts depending on the brake family. They suit home mechanics who bleed their brakes regularly and want a more complete setup ready for future servicing.
The Bleedkit SRAM Premium Mineral Edition, for example, is intended for compatible SRAM mineral-oil brakes such as DB8 and Maven. It includes fittings and bleed blocks for these newer systems and must not be used with SRAM brakes that require DOT fluid.
Bleedkit.com Workshop and Master Kits
Workshop and Master kits are designed for riders maintaining several bikes or working with more than one brake brand. They provide a broader range of adaptors, bleed blocks and spare parts than a brake-specific Basic kit.
Wider compatibility does not change the fluid rule. Mineral-oil and DOT equipment should remain separate. You will also need the correct fresh fluid for every brake system because Bleedkit.com kits are generally supplied without brake fluid.
Park Tool BKM-1.2 Mineral-Oil Bleed Kit
The Park Tool BKM-1.2 Hydraulic Brake Bleed Kit – Mineral is a workshop-quality option for servicing several mineral-oil brake systems.
It covers most compatible models from Shimano, Magura, TRP, Tektro, Trick Stuff, Campagnolo, Promax and Clarks. The standard kit also includes an adaptor for SRAM DB8 brakes.
The BKM-1.2 includes two syringes, several hose assemblies, a bleed funnel, multiple bleed blocks, adjustable syringe holders and a wide selection of threaded adaptors. Its replaceable components and organised storage case make it particularly useful for frequent servicing.
Important: SRAM Maven and other mineral-oil brakes using a Bleeding Edge-style connection may require the separate Park Tool 2602A mineral-oil Bleeding Edge adaptor. The standard BKM-1.2 specification explicitly lists SRAM DB8 but does not list Maven as standard compatibility. Confirm the brake model and required fitting before ordering.
Park Tool BKD-1.2 DOT Bleed Kit
The Park Tool BKD-1.2 Hydraulic Brake Bleed Kit – DOT is the corresponding workshop kit for compatible DOT-fluid brakes.
It is designed for most DOT systems from SRAM, Formula, Hayes and Hope. The kit includes two syringes, hose assemblies with shut-off clips, bleed blocks, adjustable syringe holders, threaded adaptors and a SRAM Bleeding Edge fitting.
The BKD-1.2 is for DOT-fluid systems only. Do not use its syringes, hoses or fittings with mineral oil, even after cleaning.
SRAM Mineral-Oil and DOT Brakes
SRAM now uses both mineral oil and DOT fluid across its brake range, so the SRAM name alone does not identify the correct kit.
- SRAM DB8 and Maven: Use the correct SRAM mineral-oil kit and mineral brake fluid.
- SRAM Code, Guide, G2 and compatible Level models: Use the appropriate DOT kit and specified DOT brake fluid.
Some SRAM brakes use a Bleeding Edge port while others use a conventional threaded connection. Check the exact model, generation and bleed-port style before choosing a kit or adaptor.
SRAM Factory Bleed Kits
A genuine SRAM bleed kit is a good option when you only service a compatible SRAM brake platform and prefer manufacturer-branded tools. The trade-off is narrower compatibility than a multi-brand workshop kit.
Make sure the kit matches both the brake fluid and the connection used by your brake. A SRAM DOT kit cannot be used on DB8 or Maven, while a SRAM mineral kit cannot be used on Code, Guide or other DOT-fluid systems.
BBB Bleed Kits
BBB offers practical alternatives for several common brake systems. These can be a good choice for occasional home servicing or when you need a straightforward kit for one compatible brake brand.
Confirm the brake manufacturer, model, fluid and bleed-port connection before ordering. A bleed kit should be selected from its compatibility information rather than its appearance.
Which Brake Bleed Kit Should You Choose?
| Situation | Best Starting Point |
|---|---|
| One bike with one known brake system | Compatible Bleedkit Basic or BBB kit |
| Regular home servicing | Bleedkit Premium kit for the exact brake family |
| SRAM DB8 or Maven | Compatible SRAM mineral-oil Bleedkit kit |
| SRAM DOT brake | Compatible SRAM DOT kit, Bleedkit DOT edition or Park Tool BKD-1.2 |
| Several mineral-oil brake brands | Park Tool BKM-1.2 or compatible Bleedkit Workshop or Master kit |
| Several DOT-fluid brake brands | Park Tool BKD-1.2 or compatible Bleedkit Workshop kit |
| Frequent or commercial workshop servicing | Separate Park Tool BKM-1.2 mineral and BKD-1.2 DOT kits |
Do You Need to Bleed Your Own Brakes?
Home bleeding can be worthwhile if you enjoy maintaining your bike, have a clean workspace and are comfortable following the brake manufacturer’s service procedure. Give yourself plenty of time for the first attempt.
A brake may need attention if the lever feels spongy, pulls unusually close to the handlebar or develops an inconsistent bite point. These symptoms can have several causes, so inspect the pads, rotor, hose and fittings as well as the hydraulic system.
Our Workshop Advice
A successful bleed depends on cleanliness as much as the tools. Use fresh fluid from a sealed container, protect the bike and keep all fluid away from the pads and rotors. Keep your mineral-oil and DOT tools clearly labelled and completely separate.
Always follow the service procedure and fluid specification published for the exact brake model. If you are unsure about compatibility or do not feel comfortable carrying out the work, bring the bike into our Christchurch workshop.
Need Help Choosing?
Bring us a photo of the brake lever and caliper or tell us the brake model and approximate year. We can help you match the bleed kit, fluid, bleed block and adaptor before you begin.
