The rear caliper brake hose carries brake fluid under pressure to the rear brake caliper. Its flexible construction allows for suspension and brake movement while maintaining a sealed hydraulic connection. A good brake hose is essential for safe braking, correct pedal feel, and reliable caliper operation.
Functions
• Replaces the rear caliper brake hose
• Carries hydraulic brake fluid to the rear brake caliper
• Supports correct rear brake pressure and pedal feel
• Allows movement between the body brake line and caliper
• Helps prevent brake fluid leaks and pressure loss
• Replaces cracked, swollen, split, leaking, or aged original hoses
• OE Match replacement for Porsche 987 rear brake service.
Why Replace This Part?
Brake hoses are exposed to brake fluid, pressure, heat, road dirt, moisture, and suspension movement. Over time, the hose can crack, swell, soften, perish, collapse internally, or leak. A failing rear brake hose may cause soft pedal feel, brake drag, reduced braking performance, fluid seepage, uneven braking, or failed inspection. Replacing the hose helps restore safe hydraulic brake operation.
When to Replace This Part
• The brake hose is cracked, swollen, soft, split, or leaking
• Brake fluid seepage is visible around the hose or fittings
• Rear brake caliper service or replacement is being carried out
• Brake pedal feel is soft or inconsistent
• Rear braking performance is weak or uneven
• The hose fittings are corroded or damaged
• Preventative replacement is being carried out during brake overhaul.
Where it fits on the car
This brake hose fits at the rear brake caliper assembly on Porsche 987 Boxster and 987C Cayman models. It forms part of the rear hydraulic braking system and connects according to the factory brake line layout.

What This Product Does
This bracket provides mechanical support at the brake hose/line mounting point. It is a retaining component, rather than a hydraulic hose or pipe, and helps keep the attached connection positioned as intended.
Functions
- Supports the brake hose/line at its mounting location.
- Helps maintain the intended routing of the connection.
- Replaces missing or damaged retaining hardware during repairs.
Technical Details
- Part reference: 113611715A.
- Brand: OE Match.
- Application position: Front/Rear, according to the vehicle assembly.
- Diagram quantities: two for each listed front or rear 911 brake line assembly; four for the 1970–73 reservoir/master cylinder assembly and the 1974–77 assembly without brake booster.
- Diagram quantities describe assembly requirements, not pack contents; supplied individually.
Symptoms of Fault
Inspect the mounting hardware if the hose/line is loose, incorrectly positioned or no longer retained at its attachment point. Hydraulic leaks, pedal changes or braking vibration require separate diagnosis and should not be attributed to this bracket alone.
Why Replacement Matters
Renewing damaged or absent mounting hardware helps restore the intended support for the brake hose/line. Compare the original bracket, attachment point and associated fixings before installation; inspect neighbouring components rather than assuming the bracket is the only item requiring attention.
OE Reference
113611715A supersedes Porsche reference 91435566500.
FAQs
Is this a brake hose?
No. It is the bracket used to retain the hose/line connection.
How many are supplied?
One bracket. Confirm the number required for the particular assembly.
Are other fittings included?
No additional contents are specified. Check the condition and requirements of the existing mounting hardware separately.

Why these should be replaced:
Flexible rubber brake hoses age with heat, road grime and brake fluid exposure — they can dry-rot, crack, bulge or leak, creating an immediate safety hazard. Even without visible leaks, inner-liner deterioration or partial collapse can cause a soft/spongy pedal and uneven braking. Replacing old hoses with correct-fit OE hoses restores reliable pedal feel and prevents catastrophic fluid loss.
Common issues & failure modes:
- External cracking / dry rot from UV, heat and age — visible on inspection.
- Fluid leaks at hose body or end fittings due to perished rubber or corroded threads.
- Internal liner collapse (not visible) — causes restricted flow, delayed pressure build and a soft brake pedal.
- Mounting damage / chafing where the hose rubs against suspension parts — can wear through the outer cover and cause sudden failure. The OEM-style support/grommet helps prevent this.
