Product Description
The 81.50213.0013+0030 F3000 Rear Brake Shoe Roller with Pin is key for F3000 heavy trucks' rear brakes. It's placed between the brake shoe and cam, cutting down friction when the cam pushes the shoe, so the shoe spreads smoothly to the brake drum, no jamming, steady braking force.
Good materials go into it: roller's high-carbon chromium steel (HRC 60-62, super wear-resistant), pin's stainless steel (no rust). Roller surface is polished and quenched-low friction, no rust. Handles 180℃ short-term heat, bumps, brake dust/moisture-no deformation, pin rust, or stuck spin. Fits F3000's original brake shoe: roller size, inner hole, and pin length match. Swap easy-no shoe/cam mods, take old out, put new set in, clip with original fastener. Tested before shipping: smooth spin, wear resistance, anti-rust-trustworthy.
Features And Advantages
Low friction, smooth: High-carbon steel roller + polished surface cuts friction, shoe spreads evenly. No uneven shoe wear, lasts 30% longer.
Tough: Quenched roller = hard + wear-resistant, stainless pin = no rust. 50k+ brakes, no excess wear/broken pins-lasts 200k+ km.
Fits F3000 exactly: Same as original-size, pin, thickness. No grinding/adjusting, saves time.
Easy install: Pre-assembled, no matching parts. Basic tools (pliers, screwdrivers) = 15-20 mins swap.
Application Scope
Only F3000 heavy trucks: tractors, dump trucks, cargo trucks. No F2000, X3000, or FAW/Dongfeng-different shoe/cam/roller sizes, won't fit.

FAQ
Q1: Works on F3000 left and right rear brake shoes?
A1: Yes, universal-left/right shoes have the same structure, no need to distinguish.
Q2: Brake squeaks after install?
A2: Check roller spins free (not stuck by the clip). If yes, grind/replace worn brake shoes. Still squeaks? Check roller damage-swap set if needed.
Q3: How often to check?
A3: Every 15k km or 6 months. Check spin, pin tightness/rust, roller wear-replace set if issues.
Q4: Lubricate the roller when installing?
A4: No-pre-coated. Extra oil attracts dust, causing jamming/wear. Install dry.
