133-8158 Brake Cable BBC Arm Kit Compatible with Toro 30" TIMEMASTER Lawn Mower 20199 20200 20975 20977 Lawn Mower-Replaces 120-6243

What It Is

The 133-8158 Brake Cable BBC Arm Kit is a replacement control cable and arm assembly that engages the blade brake and bail control (BBC) system on Toro 30" TimeMaster mowers. It stops the blades within seconds when you release the handle, a critical safety function.

Fitment & Compatibility

This kit fits Toro TimeMaster models with 30-inch decks: 20199, 20200, 20975, and 20977. It replaces OEM part 120-6243. Before buying:

• Check your model number – It’s on a sticker under the seat or near the engine. Only the four models above are confirmed compatible; other TimeMaster variants may use a different cable.
• Measure cable length – The new cable is approximately 60 inches long. Compare to your old cable; if it’s shorter or longer, this kit won’t route correctly.
• Verify brake arm condition – The kit includes the cable and a plastic BBC arm. If your old arm is intact, you may only need the cable, but this is a full assembly.
• OEM vs aftermarket – This is an aftermarket part, not Toro Genuine. Reviews note it works well, but the plastic arm may be slightly less durable than OEM.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a 10mm wrench and pliers to disconnect the old cable from the handle bail and brake lever. Expect 20-40 minutes.
• Common gotcha: The cable routing under the deck is tight. Take a photo of the old cable path before removal to avoid misrouting.
• Quality: The cable is stainless steel and holds up well; the plastic arm is the weak point. If you mow in heavy debris, check the arm for cracks after a season.
• No adjustment needed – The kit is pre-set for correct tension. If the blades don’t stop within 3 seconds, the cable may be kinked or routed incorrectly.

Should You Buy It

If your TimeMaster’s blade brake cable is frayed, stretched, or broken, this kit is a solid, budget-friendly fix. It’s not OEM, but it matches the original fit and function for about half the price. Best for DIY owners who want a reliable safety repair without dealer markup. Avoid if you need a longer-lasting plastic arm or have a non-listed model.
