Talos S78 Monoblock P4 34/34 108mm Front Left Brake Caliper | X78.108.HD.L

When the chequered flag is on the line, every metre of braking distance counts. The Talos S78 Monoblock is a race-engineered front brake caliper built without compromise — delivering the savage stopping power, granite-like rigidity and fingertip modulation that serious circuit riders demand from the very first lap.

Key Features

• Monoblock aluminium body machined from a single billet for exceptional torsional stiffness and zero caliper flex under extreme braking loads
• Four 34 mm titanium pistons with TIN (titanium nitride) coating maintain consistent bite and dramatically reduce heat transfer to the brake fluid, even across prolonged race sessions
• Hard-anodised surface finish resists corrosion, abrasion and track grime while keeping the caliper looking race-ready session after session
• Lightweight at just 589 g in the 108 mm mounting configuration — an ideal power-to-weight ratio for performance-focused builds
• 30 mm offset geometry engineered for correct disc alignment on a wide range of high-performance platforms
• Designed and rated exclusively for motorsport use — no street-use compromise in the specification

Monoblock Construction

The single-piece monoblock body is the foundation of the S78's performance advantage. By eliminating the bolted joint found in two-piece calipers, Talos removes the primary source of caliper deflection under peak braking force. The result is a direct, linear feel at the lever that allows riders to exploit the very last degree of available grip with confidence, whether they are hauling down from top speed at the end of a long straight or trail-braking deep into a hairpin.

Titanium TIN-Coated Pistons

Titanium brings a superior strength-to-weight ratio compared with stainless steel, and the TIN coating adds a further layer of protection against the thermal cycling that characterises hard track use. Reduced friction between piston and seal means less parasitic drag, longer seal life and a more progressive, consistent feel across the entire braking zone — the kind of repeatability that separates a good lap from a fast one.

Hard-Anodised Finish

The hard-anodised surface treatment goes beyond aesthetics. It creates a dense oxide layer that resists the caustic effects of brake fluid, track detritus and aggressive cleaning products. For a caliper that will see repeated track days and race weekends, this level of surface integrity translates directly into long service intervals and retained resale value.
