Product Details

Overview & Technology

Avid Juicy Caliper Service Kit (200402) brings your aging Juicy calipers back to life with a precision set of replacement pistons, piston seals and new bleed screws. The kit (Manufacturer Part #: 11.5311.550.000, SRAM Model ID: DB-SVC-CAL-A1) is designed to address common wear points that cause spongy lever feel, uneven pad retraction, or leaks. The kit's components are engineered for long-term service: precision-machined, corrosion-resistant pistons, high-temperature nitrile piston and dust seals, and stainless-steel bleed screws with sealing O-rings. Replacing these parts restores piston alignment, seal integrity and the caliper's ability to hold the correct hydraulic pressure for confident stopping on trail rides.

Key Features

Complete caliper rebuild contents: pistons, piston seals and bleed screws — everything you need to service the caliper body without buying a full replacement. Each part is matched to the original Juicy geometry to ensure correct fit and performance. Materials and construction matter: pistons are precision-machined and finished to resist corrosion and scoring; seals are made from high-temp nitrile rubber to resist brake fluid and heat; bleed screws are stainless-steel for durability and leak-free sealing. Together they reduce drag, eliminate leaks and restore crisp modulation.

Fit & Compatibility

This kit lists compatibility with Avid Juicy models from the 2005–2007 era (note available variant: 2005–2006 Juicy). Always verify your brake model and serial details before purchase — the SRAM Model ID DB-SVC-CAL-A1 and Manufacturer Part # 11.5311.550.000 are provided for reference. If you run other Juicy generations, compare caliper casting and piston sizes to confirm fit. If in doubt, contact our tech team with a photo of your caliper and mounting area — we’ll confirm fitment so you get the correct service kit for your brakes.

Who It's For

This caliper service kit is intended for mountain bikers maintaining older Avid Juicy hydraulic brakes — riders who want to restore original stopping power without replacing the entire caliper. Ideal for home mechanics, shop techs and riders preparing a bike for resale or long-season reliability. It’s also a cost-effective choice for trail riders, commuters and bikepackers who rely on predictable braking and prefer to service brakes themselves. If you notice reduced lever firmness, fluid leaks, or paddles dragging, this kit addresses the most common caliper-level causes.

Frequently Asked Questions

Will this kit fit my Avid Juicy brake caliper?

This kit is intended for Avid Juicy calipers from the 2005–2007 era (available variant lists 2005–2006 Juicy). Check your brake model and casting details and compare them to the kit part numbers (Manufacturer Part #: 11.5311.550.000, SRAM Model ID: DB-SVC-CAL-A1). If unsure, send photos of your caliper to our tech team for confirmation.

Do I need to bleed the brake after installing the kit?

Yes — replacing pistons and seals will introduce air into the hydraulic system. After assembly, perform a full bleed following the brake manufacturer's procedure to purge air and ensure correct lever feel. Use the brake fluid type specified in your brake manual.

What tools are required to install this kit?

Basic workshop tools plus a brake bleed kit are required: Torx/hex keys for caliper removal, a plastic or nylon piston press tool, picks for seal removal, clean rags, isopropyl alcohol for cleaning, and the correct bleed kit and fluid for your Avid system. A bench vise or caliper clamp can make piston reinstallation easier.

Can I reuse my old pistons or seals?

We recommend replacing pistons and seals with the new components in this kit. Old seals can harden or deform and pistons may be scored or corroded — reusing them risks leaks and poor modulation. The kit is a low-cost way to restore reliable, long-term performance.

What type of brake fluid should I use?

Always use the fluid specified by the brake manufacturer — your brake manual will list the required type. If you're unsure, consult the Avid/SRAM documentation or ask our tech team. Using the wrong fluid can damage seals and reduce braking performance.

How long does a caliper service take?

For a competent home mechanic with the right tools, a single caliper service including bleed can take 30–60 minutes. First-time jobs may take longer. Allow time for careful cleaning, inspection, and multiple bleed cycles for best results.

Buying Guide

When buying a caliper service kit, prioritize compatibility, material quality and whether the kit includes the bleed hardware you need. Matching the manufacturer's part number (11.5311.550.000 / SRAM DB-SVC-CAL-A1) is the most reliable way to ensure a correct fit. Look for high-quality pistons and seals — stainless bleed screws and nitrile or higher-grade seals extend service intervals and reduce the risk of leaks. Consider whether you prefer a full caliper replacement or a rebuild. For most riders with structurally sound calipers, a service kit is far more cost-effective and restores braking performance close to new. If caliper bodies are cracked, severely corroded or warped, replace the caliper instead of rebuilding.
