A "brake kit" bundles caliper, disc, pad, mounting hardware, and usually brake lines as one matched system — different from buying components separately. This guide covers why that match matters, how to evaluate a kit supplier, and who's building complete kits.
How to evaluate a brake kit supplier
| Question to ask | Why it matters |
|---|---|
| Is fitment verified per vehicle, or estimated by wheel size? | A bracket and bell engineered for your exact hub fits correctly the first time; a "universal" kit needing spacers usually doesn't. |
| Is the kit tested as an assembled system? | Pressure testing and disc-thickness-variation (DTV) measurement on the finished kit catches problems that testing individual parts separately can't. |
| Does one warranty cover the whole system? | Separate warranties per component (caliper, disc, lines) with different terms and gaps between them is a common way buyers end up unprotected. |
| What's actually included? | Some "kits" don't include lines, fluid, or hardware — confirm what ships before comparing price across suppliers. |
Who supplies complete kits
Brembo (Italy) sells complete GT/GTS lines spanning 4- to 6-piston front setups at OEM-tier pricing. Wilwood (USA) has the widest US aftermarket catalog — Forged Dynalite through AERO6 — covering daily-driver upgrades to dedicated track builds. StopTech (USA) bundles its own calipers, discs, and pad compounds into bolt-on ST-series kits. AP Racing (UK) sells motorsport-grade kits for track-focused builds. Baer Brakes (USA) engineers specifically around classic and modern American muscle platforms. D2 Racing (Taiwan) and K-Sport (Taiwan) compete in the mid-to-budget street-tuning tier. ICOOH (China) supplies both standard steel-disc kits and carbon-ceramic conversion kits across a wide vehicle range, at varying construction grades worth checking before comparing price.
TEi BRAKES organizes kits by use case: Street Tuned (P-series and S-series, 4–10 piston front) for daily-driven performance cars, Off-Road (T-series, 4–8 piston) for trucks and SUVs, and Racing (GT-series, one-piece forged calipers) for sprint, endurance, and track-day use. Every complete kit ships with matched calipers and discs, a vehicle-specific bell and bracket machined to order, stainless-steel braided lines, a chosen pad compound, and brake fluid — nothing sold separately that should have come in the box. Fitment is verified against a year/make/model database before the kit ships. One warranty covers the full system: 3 years on calipers, 1 year on lines, brackets, rotors, and pads — details here.
Frequently asked questions
What's included in a complete brake kit?
At minimum: a pair of calipers, a pair of discs, mounting brackets, and brake pads. Higher-quality kits also include brake lines, brake fluid, and the specific bell/bracket hardware for your vehicle — confirm this before comparing prices between suppliers.
Do I need a full kit, or can I upgrade just the calipers?
You can upgrade calipers alone if your existing discs and brackets are compatible, but mismatched sizing between a new caliper and an old disc/bracket is one of the most common DIY mistakes. A matched kit removes that risk.
How long does a brake kit take to fit my car?
Lead time depends on kit type — steel-disc kits are typically confirmed with your order (commonly 2–3 weeks), while custom carbon-ceramic discs can take significantly longer since they're machined to spec rather than pulled from stock. Check current lead times here.
