superseded by <strong>90947A2082</strong>) is the hydraulic rubber brake hose fitted to the <strong>Toyota RAV4 XA40</strong> (fourth generation, 2013&#8211;2018). The hose bridges the gap between the fixed steel brake line routed through the vehicle body and the brake caliper or wheel cylinder mounted on the moving suspension assembly &#8212; accommodating the full range of suspension travel and steering articulation while transmitting brake hydraulic pressure without restriction or volumetric expansion. The hose construction uses a rubber inner liner rated to brake hydraulic pressure, a reinforcing woven textile or steel braid layer that resists the hose from expanding under pressure, and an outer rubber cover that provides environmental protection. Toyota/Lexus catalogues this part as <strong>HOSE, FLEXIBLE</strong> and cross-references it as a brake hydraulic hose (brake line). </p> <div class="qf-spec-row"> <div class="qf-spec-item"><div class="qf-spec-label">Toyota OEM (original)</div><div class="qf-spec-value">9094702G80</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Toyota OEM (superseded)</div><div class="qf-spec-value">90947A2082</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Toyota part type</div><div class="qf-spec-value">HOSE, FLEXIBLE (Brake Hydraulic)</div></div> <div class="qf-spec-item"><div class="qf-spec-label">System</div><div class="qf-spec-value">Hydraulic brake circuit</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Weight</div><div class="qf-spec-value">0.094 kg</div></div> </div> <div class="qf-sub-head">OEM Part Number Family</div> <div class="qf-cross-grid"> <div class="qf-cross-card"><div class="qf-cross-brand">Toyota OEM (original)</div><div class="qf-cross-num">9094702G80</div><div class="qf-cross-status">&#10003; Original number &#8212; this part</div></div> <div class="qf-cross-card"><div class="qf-cross-brand">Toyota OEM (current)</div><div class="qf-cross-num">90947A2082</div><div class="qf-cross-note">Supersedes 9094702G80 &#8212; same hose</div></div> </div> <div class="qf-sub-head">Flexible Brake Hose Construction and Function</div> <p class="qf-para"> The brake hydraulic system transmits pedal force to the calipers through incompressible brake fluid under pressures of up to 150 bar during full ABS activation. The rigid steel lines that run through the body and chassis are joined to the moving suspension and steering assemblies at each corner of the vehicle by flexible rubber hoses. The 9094702G80 on the RAV4 XA40 connects the fixed steel line at the body bracket to the caliper or wheel cylinder on the suspension upright, flexing through the full suspension travel range with every road undulation and through the full steering lock range at the front axle. </p> <p class="qf-para"> The hose construction must not expand volumetrically under brake pressure &#8212; any expansion absorbs pedal travel without generating proportional caliper force, producing a soft or spongy pedal. The reinforcing woven braid inside the hose wall resists this expansion. As the hose ages, the inner rubber liner can delaminate, shedding particles into the brake fluid circuit and potentially causing one-way valve behaviour that traps hydraulic pressure in the caliper after the brake pedal is released &#8212; causing a dragging brake on the affected corner. The outer rubber cover cracks from UV, ozone, and heat exposure, exposing the reinforcing braid to corrosion and eventually allowing the liner to bulge through the damaged outer layer. </p> </div> </div> </div> <!-- BLOCK 2: SYMPTOMS & DIAGNOSTICS --> <div class="qf-block"> <div class="b-section"> <div class="b-header" onclick="qfToggle('b2')"> <div class="b-title">Symptoms &amp; Diagnostics</div> <div class="b-chevron open" id="qf-chevron-b2">&#9650;</div> </div> <div class="b-body open" id="qf-body-b2"> <div class="qf-warn-box"> <strong>&#9888; Brake hose failure is a safety-critical fault requiring immediate attention.</strong> A ruptured brake hose causes sudden loss of braking on the affected axle end or corner and full brake pedal loss if the master cylinder reservoir empties. Any brake hose showing external cracking, swelling, seeping fluid, or producing a dragging brake symptom must be replaced before the vehicle is returned to service. </div> <div class="qf-symptom"><strong>Brake fluid leak at the flexible hose body or at the banjo bolt fitting &#8212; hose failure or fitting corrosion</strong> &#8212; The most immediately visible symptom. A seeping outer layer produces a film of brake fluid on the hose surface and on the wheel rim or suspension components. Under operating pressure, a pinhole or crack may only leak when the brakes are applied &#8212; inspect with the engine running and a helper depressing the brake pedal to operate the system at pressure. Brake fluid on the inside of the wheel and visible wetness on the hose body confirm the source. A leaking banjo bolt fitting may only require retorquing the bolt and replacing the copper crush washers before condemning the hose itself.</div> <div class="qf-symptom"><strong>Spongy or soft brake pedal that has not resolved after bleeding &#8212; hose expanding under pressure</strong> &#8212; A flexible hose that has lost its reinforcing braid integrity expands outward under hydraulic pressure, absorbing pedal travel without transmitting proportional force to the caliper. The pedal sinks further than normal before generating braking force. This is distinct from air in the system &#8212; a hose expansion fault produces a consistent soft pedal that does not improve with repeated pumping, whereas air in the system improves with pumping. Confirm by having a helper apply firm sustained pedal pressure while inspecting each flexible hose for visible bulging or swelling at the hose body.</div> <div class="qf-symptom"><strong>One wheel dragging &#8212; brake caliper failing to release fully after brake pedal is released &#8212; collapsed inner liner</strong> &#8212; A delaminated or partially collapsed inner liner can create a one-way valve effect that allows pressure to pass into the caliper but prevents it from returning when the pedal is released. The affected wheel becomes hot after normal driving, the brake pads wear faster on that corner, and the vehicle may pull to one side under braking. Confirm by loosening the brake line fitting at the caliper end of the suspect hose &#8212; if brake fluid spurts out under pressure when the fitting is loosened with the pedal released, the hose is trapping pressure.</div> <div class="qf-symptom"><strong>External cracking, surface crazing, or blistering of the outer hose cover &#8212; end-of-life hose requiring proactive replacement</strong> &#8212; Visible outer layer cracking is a reliable indicator that the inner layers are at the same stage of degradation. A hose with cracked outer cover should be replaced proactively &#8212; at this stage of ageing, the inner liner is vulnerable to delamination and the reinforcing braid has reduced tensile strength. On the RAV4 XA40 in service from 2013, hoses approaching 10 years or 150,000 km should be inspected at every brake service for outer layer condition.</div> </div> </div> </div> <!-- BLOCK 3: LOGISTICS --> <div class="qf-block"> <div class="b-section"> <div class="b-header" onclick="qfToggle('b3')"> <div class="b-title">Logistics &amp; Customs</div> <div class="b-chevron open" id="qf-chevron-b3">&#9650;</div> </div> <div class="b-body open" id="qf-body-b3"> <table class="qf-logistics-table"> <tr><td>International HS Code</td><td>4009.31</td></tr> <tr><td>EAEU Customs Code (TN VED)</td><td>4009 31 000 0</td></tr> <tr><td>Net Weight</td><td>0.094 kg</td></tr> <tr><td>Country of Manufacture</td><td>China</td></tr> <tr><td>Packaging &#8212; Standard</td><td>Individual box / carton</td></tr> <tr><td>Packaging &#8212; Custom</td><td>White-label or branded &#8212; available on request</td></tr> </table> </div> </div> </div> <!-- BLOCK 4: COMPATIBILITY --> <div class="qf-block"> <div class="b-section"> <div class="b-header" onclick="qfToggle('b4')"> <div class="b-title">Vehicle Compatibility</div> <div class="b-chevron open" id="qf-chevron-b4">&#9650;</div> </div> <div class="b-body open" id="qf-body-b4"> <table class="qf-compat-table"> <thead> <tr><th>Brand / Model</th><th>Chassis / Gen</th><th>Years</th><th>Notes</th></tr> </thead> <tbody> <tr><td>Toyota RAV4</td><td>XA40 (4th gen)</td><td>2013&#8211;2018</td><td>Flexible brake hose &#8212; confirm position (rear) by VIN via Toyota parts system</td></tr> </tbody> </table> <p style="font-size:12px;color:#888;margin-top:12px;font-style:italic">The 9094702G80 was superseded by 90947A2082 in the current Toyota parts catalogue &#8212; both numbers refer to the same hose.

Toyota superseded the original catalogue number 9094702G80 with the current active number 90947A2082 &#8212; a routine Toyota parts system renumbering that occurs when a part is updated or cross-referenced. The physical hose, dimensions, fittings, and pressure rating are identical. ok.parts supplies the hose under both cross-reference numbers.

When a flexible brake hose is disconnected, air enters the hydraulic circuit at the open fitting. Air in the brake circuit is compressible &#8212; it absorbs pedal travel without generating caliper pressure, producing a low or spongy pedal. A complete bleed of the affected circuit after hose replacement is mandatory before the brakes are safe to use. Bleed until clean brake fluid with no air bubbles exits the bleed nipple on the caliper connected to the replaced hose. Check the master cylinder reservoir level throughout the bleeding process.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Should both hoses on the same axle be replaced simultaneously when one has failed?</div> <div class="qf-faq-a">Strongly recommended if the failed hose is beyond 10 years or 150,000 km of service. Both hoses on the same axle share identical service age, fluid exposure, and environmental conditions. If one has failed from age-related degradation, the other is at the same stage. Replacing both axle hoses at one service visit requires only one brake fluid drain and bleed operation per axle, saves a second lift, and ensures both corners of the axle have matching new hoses.
