Toyota's official catalogue name: <strong>"ADJUSTER SUB-ASSY, PARKING BRAKE SHOE, LH"</strong> or <strong>"Screw Set, Shoe Adjusting, LH (For Parking Brake)"</strong>. The Quattro Freni-branded aftermarket version is a comprehensive <strong>parking brake repair / installation kit</strong> that consolidates the OEM adjuster screw assembly plus matching hold-down springs, return springs, end caps, and retention hardware from 25 related Toyota/Lexus OEM references into a single complete repair kit &mdash; addressing the entire parking brake shoe mechanism in one wholesale SKU.</p> <div class="qf-info-box"><strong>Drum-in-disc (DIH) parking brake architecture.</strong> Toyota / Lexus rear axles use a <strong>hydraulic disc brake</strong> for service braking + a separate <strong>small mechanical drum brake nested inside the rear rotor's hat</strong> exclusively for parking brake function. The drum-in-disc system is distinct from conventional rear drum brakes &mdash; it has small specialised brake shoes that engage only when the parking brake lever is operated. This 47406-30040 adjuster is specifically for the drum-in-disc parking brake shoes, NOT for primary drum brakes on commercial / older Toyota applications. Drum diameter range typically 168-203 mm depending on vehicle (Camry / ES / GS / IS / SC / Supra / Land Cruiser / Sequoia).</div> <div class="qf-spec-row"> <div class="qf-spec-item"><div class="qf-spec-label">Brand part number</div><div class="qf-spec-value">Toyota 47406-30040 (4740630040)</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Toyota catalogue name</div><div class="qf-spec-value">ADJUSTER SUB-ASSY, PARKING BRAKE SHOE, LH</div></div> <div class="qf-spec-item"><div class="qf-spec-label">Position</div><div class="qf-spec-value">Rear Left (LH-only;

a threaded rod with right-hand thread at one end and left-hand thread at the other, engaging two end caps that bear against the lower shoe webs; rotating the star wheel between the end caps extends or retracts the adjuster length, changing the shoe-to-drum clearance; <strong>(2) return springs</strong> &mdash; coil tension springs that retract the shoes from the drum surface toa the parking brake lever is released; <strong>(3) hold-down springs and retainer pins</strong> &mdash; secure the shoes to the backing plate while allowing radial movement; <strong>(4) self-adjuster lever and cable connection</strong> &mdash; spring-loaded lever connected to the parking brake actuation rod that advances the star wheel by one tooth when parking brake travel exceeds a threshold, automatically compensating for lining wear.</p> <p class="qf-para">Operation: <strong>lever pulled</strong> &rarr; cable tension transferred to rear actuator levers &rarr; shoes contact drum inside rotor hat &rarr; parking brake hold. <strong>Lever released</strong> &rarr; return springs retract shoes. <strong>Self-adjustment</strong>: as lining wears, lever travel increases; when travel exceeds threshold, mechanism rotates star wheel one tooth, restoring correct clearance.</p> <p class="qf-para">Three failure mechanisms: <strong>(1) thread corrosion seizure</strong> from salt / moisture &mdash; adjuster cannot extend, lever travel grows excessive; <strong>(2) star wheel tooth stripping</strong> from overtightening &mdash; adjuster permanently fixed; <strong>(3) end cap bearing face wear</strong> &mdash; adjuster tilts, asymmetric load cracks body. The Quattro Freni kit format addresses all related hardware simultaneously, preventing repeat failure from accompanying corroded springs / pins / clips.</p> </div> </div> </div> <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-symptom"><strong>Parking brake lever requires excessive travel / clicks to engage</strong> &mdash; The lever click count exceeds normal (typically 3-5 clicks for Toyota / Lexus designs); lever feels increasingly "long" before engaging. Adjuster has seized in its current position and shoe-to-drum clearance has grown as lining has worn. <strong>Most common Toyota / Lexus parking brake fault symptom</strong>.</div> <div class="qf-symptom"><strong>Parking brake fails to hold vehicle on gradient that it previously held</strong> &mdash; The lever travels to its full extent but cannot generate sufficient shoe-to-drum contact pressure due to excessive clearance. <strong>Safety critical</strong>: vehicle may roll on gradient despite parking brake engagement. Address immediately.</div> <div class="qf-symptom"><strong>Star wheel will not turn when accessed through backing plate slot &mdash; or requires excessive force</strong> &mdash; Adjuster thread is corrosion-seized. Apply penetrating oil through backing plate slot, allow extended soak time before attempting rotation. <strong>If still resists</strong>: adjuster requires removal and replacement; forcing seized star wheel strips teeth and leaves adjuster permanently fixed.</div> <div class="qf-symptom"><strong>Rattling from rear brake area during light braking</strong> &mdash; Metallic rattle reduces when parking brake lightly applied. Adjuster backed off; shoe-to-drum clearance grown. Confirm by removing rotor and inspecting adjuster extension.</div> <div class="qf-symptom"><strong>Asymmetric parking brake &mdash; one wheel locks, other free</strong> &mdash; One adjuster seized or star wheel stripped; equaliser cannot compensate. <strong>Replace adjusters AS A PAIR</strong> &mdash; LH + RH simultaneously.</div> <div class="qf-symptom"><strong>New shoes fitted but drum / rotor cannot be reinstalled</strong> &mdash; Adjuster was not retracted to minimum before fitting new shoes. Retract fully via star wheel before installation. NEVER force drum over un-retracted shoes; damages drum and linings.</div> <div class="qf-info-box"><strong>Diagnosis sequence:</strong> (1) <strong>Count lever clicks</strong> &mdash; >5-7 on system designed for 3-5 = adjuster fault. (2) <strong>Test parking brake hold on gradient</strong>. (3) <strong>Access star wheel through backing plate slot</strong> &mdash; serviceable turns freely; seized = no movement. (4) <strong>Remove rotor</strong> for direct inspection. (5) <strong>Inspect</strong>: adjuster extension, thread condition, end cap wear, spring fatigue, pin corrosion.

The Quattro Freni kit format consolidates <strong>25 related OEM references</strong> into a single repair kit, simplifying inventory and ensuring no component is missed during repair.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Are parking brake shoes themselves included with this kit?</div> <div class="qf-faq-a"><strong>No</strong> &mdash; this kit includes adjuster assembly + springs + retention hardware but does NOT include the parking brake shoes themselves. Order parking brake shoes separately if shoe replacement is required. Toyota parking brake shoe set references vary by application: <strong>46550-30070</strong> (Camry / ES), <strong>46550-60040</strong> (Land Cruiser / Sequoia), and others depending on vehicle. Cross-check shoe set reference with your specific Toyota / Lexus model. Inspect existing shoe lining thickness during kit installation &mdash; minimum 1.5-2.0 mm; below this = shoes also require replacement.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Does this kit fit Toyota / Lexus vehicles with electric parking brake (EPB)?</div> <div class="qf-faq-a"><strong>No</strong>. EPB systems use electric motors on rear calipers; no drum-in-disc mechanism. EPB applies: many Lexus from ~2010 (LS / GS / IS / RX / NX), Toyota from ~2015 (RAV4 / Highlander / Avalon). <strong>Verify mechanism</strong> by inspecting under-vehicle through backing plate slot &mdash; small drum inside rotor hat = drum-in-disc (kit fits); smooth rotor hat = EPB (does NOT fit).</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Should LH and RH adjusters always be replaced as a pair?</div> <div class="qf-faq-a"><strong>YES &mdash; mandatory.</strong> Both rear parking brake adjusters accumulate identical corrosion and wear from same environmental exposure. If one adjuster has seized, the opposite side is at the same corrosion stage and will seize within a short interval. Replacing both during a single rear-rotor removal operation: (1) ensures symmetric parking brake performance; (2) eliminates a second rotor removal labour cost within a short mileage; (3) prevents the asymmetric parking brake fault syndrome (one wheel locks, other free). Order kit pair: <strong>47406-30040 LH (this part)</strong> + <strong>47405-30040 RH (mirror counterpart)</strong>.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Is white-label or custom packaging available for Toyota / Lexus specialists?</div> <div class="qf-faq-a">Yes. Quattro Freni-branded packaging is default; white-label or custom-branded packaging with company logo / part numbers / barcode available for wholesale. The 25-OEM consolidation format is a strong wholesale proposition for Toyota / Lexus specialists, multi-brand independents, brake distributors. JDM variants expand market.
