Ultima Rear Brake Wheel Cylinder LHS R/L (JB3158) for Toyota Dyna BU6# & BU100 Single Rear Tyre 1985–1999

This Ultima Rear Brake Wheel Cylinder (JB3158) is designed as a high-quality, direct OE replacement for the Rear Left-Hand Side (LHS) of specific Toyota Dyna light truck models equipped with **Single Rear Tyres (SRW)**. This part is the **Rear/Lower (R/L) or Trailing Shoe** cylinder, which works in tandem with the leading shoe cylinder (JB3156) on the same axle. It fits the Dyna BU6# series (January 1985 to December 1988) and the BU100 series (July 1995 to May 1999). It is crucial to confirm your vehicle uses single rear tyres, as dual-tyre models may require a different part. This cylinder is a vital component in the rear drum brake system, converting hydraulic pressure into the necessary stopping force required by the brake shoes to ensure safe and dependable performance under load.

Features & Benefits:

  • Direct Fit OE Replacement: Designed to match the fit, form, and function of the original equipment wheel cylinder on the LHS Trailing Shoe position.
  • Single Rear Tyre Specific: Correct fitment for Dyna models that are not dual-rear-wheel (DRW).
  • Heavy-Duty Construction: Built for durability and dependable braking performance in light commercial use.
  • Reliable Braking: Ensures accurate hydraulic pressure transfer for consistent and responsive drum braking performance.
  • Corrosion Resistance: Manufactured from durable materials for protection against corrosion and wear.
  • Position Specific: Designed exclusively for the Rear Left-Hand Side (LHS), Trailing/Lower Shoe.
  • Complete Unit: Supplied ready to install with pistons, seals, and boots.

Good quality 😍
Color: Ice Green, Size: Large
I really like this shirt! The knit material feels soft, breathable, and perfect for warm weather. The design looks stylish and modern, exactly like the pictures. It fits true to size and sits really nice on the body—comfortable but still fitted enough to look clean. Great for summer outings, brunch, or beach vibes. Definitely worth the purchase
