Brake fluid reservoir

A wet patch under the bonnet or fluid dropping faster than it should are common signs of a cracked brake fluid reservoir. Finding the right replacement isn't easy. The reservoir has to match the master cylinder and the fluid capacity. Most buyers end up checking three or four marketplace pages, re-entering vehicle details each time, and struggling to tell from photos whether the connector or outlet ports match.Parthunt24 brings together used brake fluid reservoir listings from marketplaces like eBay, Ovoko, RicambiPro, Opisto, Proxyparts, Ecooparts, Autoparts-24, Totalparts. Compare 42 options on price, condition, and fitment, then go to the marketplace once you're ready to buy brake fluid reservoir replacements.

The brake fluid reservoir sits at the top of the master cylinder, usually mounted on or near the firewall at the rear of the engine compartment. It's almost directly in front of where the brake pedal mounts on the other side of the bulkhead, and is often the most accessible part of the brake hydraulic system. On Parthunt24, narrow your search by OEM code or vehicle, then refine with the Category, Manufacturer, Series, Model, Modification, and Price filters. Each listing redirects to the marketplace, with the full description and order button on the seller's page.Check the listing for each of these:

• Vehicle compatibility: Match make, model, year, and engine variant exactly.
• Master cylinder compatibility: Reservoir fits the specific brake master cylinder, shape, seal type.
• Mounting type: Direct mount vs remote reservoir with hoses.
• Capacity / volume: Correct fluid capacity for the braking system.
• Sensor compatibility: Fluid level sensor presence, connector type, and pin configuration.
• Outlet ports: Correct number and position of fluid outlets.
• Cap type and seal: Cap design, sealing quality, and compatibility.
• Material: Typically plastic; check for heat resistance and durability.
• Hose compatibility, remote type: Hose diameter and connection points.
• Condition, if used: Inspect for cracks, discoloration, leaks, and damaged threads.

Once you've clicked through, the spec might be right but the seller and the small print decide whether it's worth the money. Brake fluid reservoirs crack along stress lines that don't always show in catalogue photos, so the listing needs to be detailed enough to be confident. Run through these:

• Photos: Body, cap, outlet ports, and sensor connector.
• Seller reputation: Ratings, reviews, and trading history.
• Compatibility: Part numbers or cross-references.
• Included components: Reservoir only, or with cap, sensor, or grommets?
• Condition: Cracks, discolouration, or thread damage.
• Testing: Notes confirming the seller pressure-tested it.
• Warranty and returns: A clear policy if it leaks on arrival.
• Shipping: Padded packaging to protect the body.
• Documentation: Donor vehicle details or proof of origin.

If it checks out, place the order directly with the seller.

Brake fluid reservoir price depends on the vehicle, the master cylinder, and whether a sensor is included. A simple used reservoir for a common car starts around €10, mid-range listings with a level sensor sit at €20-€60, and OEM brake fluid reservoir price for premium vehicles can climb past €120. Comparing prices on Parthunt24 is the fastest way to spot the best deal.On Parthunt24, find a brake fluid reservoir from as low as 5.00. The brake fluid reservoir price gap between listings often comes down to factors the headline price doesn't show:

• Sensor: Reservoirs with a working float sensor cost more than basic units.
• Mounting type: Remote reservoirs with hoses cost more than direct-mount tanks.
• Brand: OEM sits at the top; quality aftermarket sits below.
• Vehicle rarity: Common cars are cheaper; specialist vehicles cost more.
• Condition: Crack-free units command a brake fluid reservoir price premium.

The cheapest listing isn't always the best buy. A missing cap or worn sensor can push a low-price option higher than a complete unit, which the Parthunt24 comparison view brings out clearly.

A leaking reservoir rarely goes wrong on its own. Cracks usually point to age, heat damage, or contamination affecting other parts of the brake system. Browse these on Parthunt24 alongside the reservoir:

• Master cylinder: Often fails alongside the reservoir if seals are old.
• Reservoir cap: Cheap, easily lost, and worth replacing on a swap.
• Brake pads: Worn brake pads cause low fluid level warnings that mimic reservoir issues.
• Brake booster: Vacuum faults can show up alongside reservoir issues.
• Drum brakes: Low fluid on rear-drum systems can point to wheel cylinder leaks.
• Brake lines and hoses: Perished hoses leak fluid that ends up blamed on the reservoir.
• Fluid level sensor: Often integrated; check the float before swapping the tank.
