Rear Drum Brake Kit (E21)
Rear Drum Brake Kit (E21)
This 250mm rear brake upgrade kit, when used with our vented rotor front upgrades gives a very nice brake balance right out of the box. It offers a substantial increase in braking over the stock 230mm drums. Includes good used E21 backing plates (powder-coated semi-gloss black), and new drums, cylinders, shoes, springs, and all brake hardware. This is a simple bolt-on upgrade. you will need to trim the parking brake cable tube by approximately 1 cm where it exists the body to allow for proper parking brake lever angle when activated.
We recommend installing a 2002tii master cylinder if you are installing a vented brake upgrade and rear drum kit. The Tii unit pushes more fluid to the larger front calipers and rear wheel cylinders. The ATE master cylinder kit includes 2 new upper grommets.
When utilized with a standard “big brake” conversion in the front (with semi-metallic pads or similar), the rear disc semi-metallic or metallic brake pads should provide near optimum brake bias (all four wheels lock at the same time). In the event that you rear lock up prior to front lock up, it may be necessary to either change to a higher friction front pad or to install a brake bias adjuster (usually $40 - $50) to reduce the effective rear braking. This assumes, of course, that braking components are in good working order. If you have questions, please contact us.
