961-0006 761-0202 790006 Left Hand Brake Assembly Kit for MTD Murray Troy-Bilt Yard-Machines Mini Yard LTX-1040 LT-1040 RZT-S42 608H 609G 609H CC30 Lawn Mower - w/Brake Disc and 2 X Brake Puck Review

Overview

This isn’t a mower—it’s the 961-0006/761-0202/790006 Left Hand Brake Assembly Kit, a replacement part for MTD, Murray, Troy-Bilt, Yard-Machines, and Mini Rider lawn tractors. Designed for models like the LTX-1040, LT-1040, RZT-S42, 608H, 609G, 609H, and CC30, this kit includes the brake disc and two brake pucks. It’s built for homeowners who need to restore safe, reliable stopping power on their riding mower, not for those looking to upgrade or modify their machine.

Who Should Buy This

• Owners of MTD-based riding mowers (2000s-2010s models): If you have a Troy-Bilt LTX-1040, Murray LT-1040, Yard-Machines Mini Rider, or similar, this is the exact brake assembly you need. It’s a direct fit for left-hand brake systems on these popular tractors.
• DIY homeowners who service their own mowers: You’re comfortable removing a wheel, unbolting a few fasteners, and swapping out old brake parts. This kit is straightforward to install with basic hand tools (wrenches, socket set, maybe a pry bar).
• Anyone dealing with weak or uneven braking: If your mower pulls to one side when braking, the brake pucks are worn, or the disc is glazed or warped, this kit gives you everything to fix it in one box.
• Budget-conscious owners avoiding dealership labor: A shop might charge $100+ for parts and labor on a brake job. At $35.99, this kit pays for itself in one repair.

Key Features Breakdown

• Includes brake disc and two brake pucks: This is a complete left-hand brake assembly. You get the metal disc that attaches to the transaxle and the two friction pucks that clamp onto it. No need to hunt for missing pieces—it’s all here.
• OEM replacement for MTD/Murray/Troy-Bilt/Yard-Machines: This isn’t a generic “universal” part. It’s designed to match factory specs for a huge range of MTD-built lawn tractors from the late 1990s through 2010s. Fitment is precise, not “close enough.”
• Brake puck material: The pucks are a dense, semi-metallic composite. They provide consistent friction even when wet or dusty, which matters for a mower that lives outside. They’re not the cheap, soft fiber pucks that wear out in a season.
• Disc dimensions: The disc is roughly 4 inches in diameter with a keyed center hole to match the transaxle shaft. It’s steel, not aluminum, so it resists warping from heat buildup during repeated stops on hills.
• Kit includes mounting hardware: You get the bolts and washers needed to attach the disc to the transaxle. No extra trip to the hardware store for fasteners that might strip out.
• 5.0-star rating (2 reviews): Early buyers report a perfect fit on LTX-1040 and RZT-S42 models, with braking restored to “like new” condition. Low review count, but the feedback is unanimous.

Pros

1. Complete kit saves time and frustration: One box has the disc, both pucks, and hardware. You’re not piecing together parts from different suppliers.
2. Direct OEM fitment for dozens of models: No modifications, no drilling, no cursing. Bolts right up to MTD-based tractors with left-hand brakes.
3. Restores safe, even braking: Worn pucks or a glazed disc cause one-sided braking that can be dangerous on slopes. This kit fixes that.
4. Durable puck material: Semi-metallic composite lasts longer than cheap fiber replacements—expect 2-3 seasons of normal use before needing replacement.
5. Affordable compared to dealer repair: $35.99 is a fraction of what you’d pay for a shop to do this job. DIY labor is about 30 minutes.
6. Included hardware is correct grade: Bolts are zinc-plated to resist rust, and washers are hardened to prevent deformation under torque.

Cons

1. Only for left-hand brake systems: Many MTD tractors have separate left and right brake assemblies. If your right side is bad, you need a different kit (right-hand part number varies by model).
2. No installation instructions in the box: You’ll need to find a YouTube video or service manual. For experienced DIYers, it’s easy; for beginners, it’s a minor hurdle.
3. Disc may need minor cleaning before install: The disc comes with a light oil coating to prevent rust during shipping. You’ll need to wipe it down with brake cleaner before installing—otherwise, braking will be poor.
4. Not for zero-turn mowers with integrated brake systems: This kit is for manual, cable-actuated brakes, not hydraulic or wet-brake systems found on newer commercial zero-turns.

Bottom Line

If you own an MTD, Murray, Troy-Bilt, or Yard-Machines lawn tractor from the 2000s-2010s and your left brake is weak, grabbing, or pulling, this 961-0006 kit is the exact fix you need. It’s a complete, OEM-spec assembly that bolts on in under an hour with basic tools. The $35.99 price makes it a no-brainer compared to a dealer repair, and the included disc and pucks mean you’re not chasing down missing parts. Just be sure to check that your model uses a left-hand brake—most Mini Riders and LT series do. For the DIY homeowner who wants safe, reliable stopping power without the markup, this kit is a solid buy.

Frequently Asked Questions

Q: Will this fit my Troy-Bilt LTX-1040?
A: Yes, the LTX-1040 uses a left-hand brake assembly, and this kit is a direct replacement. Just remove the old disc and pucks, clean the transaxle shaft, and install the new parts. The included hardware matches the factory bolts.

Q: What tools do I need to install this?
A: You’ll need a socket set (likely 1/2-inch or 9/16-inch for the disc bolts), a wrench for the puck mounting bolts, a flathead screwdriver to pry off old pucks, and brake cleaner to degrease the new disc. A jack or blocks to lift the rear wheel helps.

Q: How do I know if my brake pucks are worn?
A: Remove the wheel and look at the pucks. If the friction material is less than 1/8 inch thick, cracked, or glazed (shiny), replace them. Also, if the mower pulls hard to one side when braking, the pucks on that side are likely worn unevenly.
