Brake Caliper & Hydraulic Repairs in Adelaide

About This Service

The hydraulic side of your braking system is what turns pedal pressure into stopping force. When a caliper seizes, a master cylinder fails, a brake line corrodes through, or the fluid absorbs enough moisture to lower its boiling point — your stopping distances increase, your vehicle may pull to one side, and in the worst cases, your brakes can fail entirely under hard use.

All Clutch & Brake has repaired brake calipers and hydraulic systems in Adelaide since 1984. We are not a general mechanic shop — brakes and clutch systems are all we do. That specialisation means our team has seen every hydraulic failure mode on every vehicle type, and can diagnose the root cause correctly the first time rather than replacing parts until the problem goes away.

Signs Your Brake Calipers or Hydraulic System Need Attention

The following symptoms each point to a specific failure in the caliper or hydraulic system — understanding which symptom you have helps target the diagnosis:

Vehicle pulls to the left or right under braking — typically a seized caliper on the pulling side holding the pad against the rotor when the brake is released, or a caliper that is not releasing fully on one side.
Brake pad wearing faster on one side than the other — a stuck piston in a caliper causes constant pad-to-rotor contact on that corner, wearing the pad to nothing while the other side remains thick.
Soft, spongy, or low brake pedal — indicates air in the hydraulic system (from a leak, low fluid, or a failed master cylinder seal), or a master cylinder that is bypassing internally.
Brake pedal sinking slowly to the floor under constant pressure — a classic internal master cylinder seal failure. The pedal feels firm initially but gradually sinks as the worn seal allows fluid to bypass the piston.
Fluid pooling behind a wheel, on the inside of a tyre, or visible brake fluid on the caliper body — a leaking caliper piston seal or dust boot. Brake fluid on a hot rotor or pad causes a significant reduction in braking performance.
Burning smell and excessive heat from one wheel after normal driving — a fully seized caliper with the pad continuously dragging against the rotor, generating heat that can warp the disc and overheat the wheel bearing.

Brake Caliper Reconditioning and Replacement

When a brake caliper fails — whether from a seized piston, a torn dust boot, a leaking seal, or corrosion — there are two options: rebuild (recondition) the existing caliper or replace it entirely. We assess the caliper's condition to determine which path is correct for your vehicle and budget.

Caliper rebuild: we disassemble the caliper, clean and inspect the bore, replace the piston seals, dust boots, and bleed nipple, and reassemble to factory specification. A correctly rebuilt caliper performs identically to a new unit. We rebuild front and rear calipers, single-piston sliding calipers, and multi-piston fixed calipers on performance applications.

Caliper replacement: when a caliper body is cracked, corroded beyond rebuild tolerance, or no longer within bore specification, replacement with a quality remanufactured or new unit is the correct option. Replacement calipers are sourced from reputable suppliers — we do not fit unbranded or low-grade units on safety-critical components.

Master Cylinder and Slave Cylinder Repairs

The master cylinder is the heart of your hydraulic braking system. It converts the mechanical force of your foot on the brake pedal into hydraulic pressure that travels through the brake lines to each caliper or wheel cylinder. When the master cylinder's internal seals wear — which they do over time and with heat cycling — the pedal gradually sinks under sustained pressure, a symptom that most drivers initially dismiss as "the brakes need adjusting."

We diagnose master cylinder failure by pressure-testing the hydraulic system and performing a bench test of the cylinder itself where required. In most cases on modern vehicles, master cylinder replacement is more practical than rebuild due to the precision tolerances involved. Following replacement, we bleed the full hydraulic circuit including any ABS modulator — the ABS bleed procedure requires cycling the ABS pump through its solenoids in the correct sequence, which differs from a standard gravity or pressure bleed.

We also repair brake slave cylinders on drum brake rear axles — the wheel cylinder that pushes the brake shoes against the drum. Leaking wheel cylinders cause fluid contamination of the brake shoes, resulting in severely reduced rear braking performance and uneven braking across the axle.

Brake Line and Brake Hose Replacement

Brake lines run from the master cylinder to each corner of the vehicle. The rigid sections are steel or stainless hard-lines; the flexible sections between the hard-line and the caliper are rubber or braided stainless hoses that flex with suspension movement. Both fail over time — hard-lines through external corrosion (more common in older vehicles or those in coastal environments), rubber hoses through internal deterioration that can cause the hose to act as a one-way valve, applying pressure normally but preventing full release, which causes a caliper to hold on after the pedal is released.

We replace both rigid hard-lines and flexible hoses. For modified 4WDs, lifted vehicles, and performance builds where standard hose lengths are insufficient, we fabricate custom brake hoses to the correct ADR-compliant specification.

See our Custom Brake Hoses page for detail on hose fabrication for lifted, modified, and performance vehicles.

Brake Fluid Flush and Hydraulic System Bleeding

Brake fluid is hygroscopic — it absorbs moisture from the atmosphere over time. As the fluid's moisture content rises, its boiling point drops. Fresh DOT 4 fluid has a dry boiling point of approximately 230°C. Brake fluid with 3% water content drops to around 155°C — below the temperature your brake system can reach under hard or sustained use. When fluid boils, it vapourises and introduces air into the hydraulic circuit, causing the pedal to go soft or fade entirely. This is brake fade caused by vapour lock, and it happens suddenly.

We use the correct DOT-rated fluid for your vehicle — DOT 3, DOT 4, or DOT 5.1 depending on the manufacturer specification. We do not substitute a lower-rated fluid to save cost. For ABS-equipped vehicles, we bleed each corner in the correct sequence and cycle the ABS pump and solenoids to purge any air trapped in the modulator — a step many workshops skip because it requires scan tool access to the ABS system.

Hydraulic Clutch System Repairs

Most modern manual transmission vehicles use a hydraulic clutch system — a clutch master cylinder, clutch slave cylinder, and connecting line — that operates on the same hydraulic principles as the brake system. When the clutch pedal becomes heavy, spongy, or stays on the floor, the hydraulic clutch circuit is usually the cause.

Because All Clutch & Brake specialises in both brake and clutch systems, we are one of the few workshops in Adelaide equipped and experienced to carry out hydraulic clutch repairs alongside brake hydraulic work. We repair and replace clutch master cylinders, external slave cylinders, concentric slave cylinders (CSC) mounted inside the bell housing, and clutch hydraulic lines.

Brake Booster and Hydrovac Testing and Repair

The brake booster (or hydrovac on heavy commercial vehicles) multiplies the force of your foot on the pedal before it reaches the master cylinder. A failing brake booster makes the pedal extremely hard to press and significantly increases stopping distance — you are effectively braking without any assistance. A hissing sound from the engine bay when the brake pedal is pressed, or a pedal that requires noticeably more force than usual, both indicate booster failure.

We test brake boosters and hydrovac units in-house and carry out repairs where the booster can be serviced. For units beyond economic repair, we source replacement units and carry out the full installation including adjustment of the pushrod clearance between the booster and master cylinder — a dimension that is critical to correct pedal feel and is often overlooked on DIY replacements.

Contact All Clutch & Brake on 08 8277 8122 for an accurate quote specific to your vehicle.

Book Your Brake Caliper or Hydraulic Repair in Adelaide

Do not drive a vehicle with a known caliper or hydraulic failure. A seized caliper generates enough heat to warp your rotor, overheat your wheel bearing, and in extreme cases ignite brake dust and debris around the wheel. A failed master cylinder can cause total loss of braking under heavy use. Both are genuine safety emergencies.

Call All Clutch & Brake on 08 8277 8122 or bring your vehicle to Unit 1/3 Adelaide Terrace, St Marys SA 5042. Comprehensive inspection, precise diagnosis and quote before any work begins.
