In disc systems with low-mounted master cylinders, a 2 lb valve keeps the system primed without dragging the pads. In harsh vibration environments, a 4 lb valve improves pedal consistency, while drum brake systems require a 10 lb valve to overcome return spring pressure and maintain proper sealing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e","brand":"Wilwood","offers":[{"title":"2 LB","offer_id":56313403670694,"sku":"WIL260-13706","price":22.79,"currency_code":"USD","in_stock":true},{"title":"4 LB","offer_id":56313403703462,"sku":"WIL260-15365","price":25.39,"currency_code":"USD","in_stock":true},{"title":"10 LB","offer_id":56313403736230,"sku":"WIL260-13707","price":22.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8394\/6406\/files\/WIL260-13706-Residual-Pressure-Valve-1.jpg?v=1776886875","url":"https:\/\/wideopendesign.com\/products\/wilwood-residual-pressure-valve-new-style-2-blue","provider":"Wide Open Design","version":"1.0","type":"link"}
