with rigid brake lines since the caliper is fixed to the chassis and doesn&#8217;t move with the wheel. A hard line can manage a higher hydraulic pressure versus a flexible hose on outboard brakes so, in theory, inboard configurations provide higher braking torque per a given size of rotor (but a flexible line is still required from the chassis to the suspension cage).<\/p>\n<p>There are disadvantages, too. Rotors get very hot and the inboard location means that rotor heat is more readily transmitted to the differential which puts added stress on drivetrain oil seals (differential oil leaks are not uncommon on XJ models). Of perhaps more importance is the hassle of maintenance. Inboard brake rotors cannot be easily replaced like outboard ones; the entire axle must be removed first! Inboard brake pads can be changed, but not as conveniently as an outboard setup. Bleeding inboard brakes can be a chore as well.<\/p>\n<div id=\"attachment_2179\" style=\"width: 1210px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/krissmotors.com\/XJ6\/wp-content\/uploads\/restored-caliper.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-2179\" src=\"https:\/\/krissmotors.com\/XJ6\/wp-content\/uploads\/restored-caliper.png\" alt=\"\" width=\"1200\" height=\"900\" class=\"size-full wp-image-2179\" srcset=\"https:\/\/krissmotors.com\/XJ6\/wp-content\/uploads\/restored-caliper.png 1200w, https:\/\/krissmotors.com\/XJ6\/wp-content\/uploads\/restored-caliper-330x248.png 330w, https:\/\/krissmotors.com\/XJ6\/wp-content\/uploads\/restored-caliper-768x576.png 768w, https:\/\/krissmotors.com\/XJ6\/wp-content\/uploads\/restored-caliper-1024x768.png 1024w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/a><p id=\"caption-attachment-2179\" class=\"wp-caption-text\">Restored rear caliper with new EBC rotor and Greenstuff pad<\/p><\/div>\n<p>It is possible to convert an XJ6 from inboard to outboard brakes, but this requires new half shafts and other fittings.

A solid rotor can reach 400-1000\u2109 when brakes are applied; a rotor with vents (and\/or slots and drilled holes) tends be about 50-200\u2109 cooler under the same conditions. That translates into less heat conducted into the differential case and less stress on the oil seals. Cooler rotors have the added benefit of minimizing brake fade, but this isn&#8217;t of much concern on the rear brakes since most of the stopping friction is handled by the front brakes.<\/p>\n<p>The Jaguar rotors, both front and rear, are only 1\/2&#8243; in diameter, so this means that solid rotors must be used (there isn&#8217;t room for a vented middle air space) unless the calipers are modified to handle a larger rotor diameter. This isn&#8217;t practical and not worth the minor improvement due to a lower heat generation of a vented rotor. So the best Jaguar choice is a solid (non-vented) rotor with some sort of heat mitigation due to the application of slots, dimples, and holes.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"EBC\"><\/span>EBC<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Numerous variations of vents, slots, dimples, and holes populate the brake rotor world. EBC, a major worldwide brand with high quality standards and exclusive UK\/USA manufacturing facilities, has developed solid rotors with a combination of slots and surface dimples that balances heat dissipation, strength, and performance.<\/p>\n<div id=\"attachment_2230\" style=\"width: 190px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/krissmotors.com\/XJ6\/wp-content\/uploads\/80-gd.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-2230\" src=\"https:\/\/krissmotors.com\/XJ6\/wp-content\/uploads\/80-gd.jpg\" alt=\"\" width=\"180\" height=\"205\" class=\"size-full wp-image-2230\" \/><\/a><p id=\"caption-attachment-2230\" class=\"wp-caption-text\">EBC solid gold<\/p><\/div>\n<p>EBC invented a dimple drilled rotor in the 1990s (and widely imitated since) to provide pad degassing without weakening the disc by drilling through holes that can promote rotor cracks.
