Leeroy Posted June 1, 2010 Share Posted June 1, 2010 I checked my front pads this weekend and it turns out there aren't any anti-squeal shims fitted. They're the standard Brembo calipers and I'll be putting some Ferrodo DS2500 pads in soon. Does anyone have any spare shims knocking around? Cheers Leigh.

introspect Posted June 1, 2010 Share Posted June 1, 2010 You could always use it as an excuse to upgrade to these http://www.350z-uk.com/forum/viewtopic.php?f=32&t=28634&p=505548&hilit=titanium+brake+shims#p505548 Not sure how much standard shims are but I'm sure ZMANALEX could supply them too if you don't want to go for the titanium.

Before the complete brake upgrade I was running the Ferrodo DS2500s with no shims on the Brembo rotors I knew I was going to be replacing the rotors relatively soon though Quote Link to comment Share on other sites More sharing options...

andlid Posted June 1, 2010 Share Posted June 1, 2010 rake shims are thin layers of rubber or metal that fit between the brake pads and the rotors to correct small imperfections that cause brake noise. They function just like shims in cabinetry: If the kitchen floor of an old house is a little crooked, the cabinet installer will add a couple of thin, wooden shims to level out the cabinets. Brake shims work much the same way to adjust otherwise normal brakes. On the most basic level, for many new vehicles with new brake parts, brake shims function as anti-rattle pads. They keep the pads and rotors from banging against each other or squealing. Some brake part kits come with the shims already attached to the brake pads; some come with separate shims that have adhesive backings, which need to be affixed to the back of the brake pads. Other shims must be purchased separately and attached to the pads with double-sided tape. In anÂy case, brake shims are easy to use and install, and they can make a big difference in the way that the brake parts work together. While most are made from rubber, it's possible to upgrade to something like titanium brake shims. Let's take a look at these as an option for a brake shim upgrade. Titanium Brake Shims Brakes are tested under extreme conditions. Titanium brake shims work as heat shields to maintain braking power. When brakes are under stress, they get hot. Real hot. Just think how hot the brake parts on a racecar get when coming out of a straight stretch to enter a corner. Rubber can quickly turn to goo in that situation, or in any heavy braking scenario. The heat created from the friction of the hard-working brakes can actually boil the hydraulic brake fluid, which even further reduces stopping power. That's where titanium brake shims come in. Titanium brake shims work like heat shields to prevent the heat of the braking effort from affecting the other brake parts. Manufacturers often use a titanium alloy in the brake shims to keep costs down, as titanium can be very expensive. While rubber brake shims can be stuck to the back of brake pads using two-sided tape, titanium brake shims are usually secured by other means. They often have holes at the top and thread onto the caliper pins. They still fit between the brake pads and the rotors, but they function less as noise dampeners and more as heat shields. ÂKeeping the brake parts as cool as possible means a longer life for brake parts and fewer brake fluid changes. Brake shims are great for cars, but what about motorcycles? Can one brake part make a difference in the safety of a bike? Of course it can. Motorcycle Brake Shims In addition to shielding heat and reducing noise, motorcycle brake shims are an important alignment aid. If a wheel isn't perfectly centered, a motorcycle brake shim inserted between the brake and rotor can bring it to true. motorcycle brake shims Motorcycle brake shims help with alignment and reduce noise. Since motorcycles don't usually generate the kind of heat that racecars do, the types of motorcycle brake shims you'll find are usually of the stick-on rubber variety, rather than titanium. These rubber brake shims reduce noise and vibration, making for a more comfortable ride. They also protect the brake pistons from overheating, which improves safety. The shims also function to snug the friction surface of the brake pads against the rotors. The more of the friction surface that comes into contact with the rotors, the more stopping power the brake parts will be able to generate. Though the humble brake shim serves a simple purpose and sometimes is an underestimated brake part, its assistance in wheel alignment and bettering maximum braking power is important. It helps reduce uneven wear and tear on brakes and increases the safety, giving both bike and rider a smoother and more comfortable ride.

ATTAK Z Posted June 1, 2010 Share Posted June 1, 2010 I can understand why you'd need shims on brakes with a floating calliper but not why they would benefit brakes such as the Brembos which have moving pistons on both sides of the rotor ........They [the shims] still fit between the brake pads and the rotors ...................

Same thing really... shims on a floating calliper with active pistons on one side only - yes I can see that helps to align the braking effort and prevent the active piston from bending the rotor as it pushes the rotor towards the inactive pad shims on a Brembo calliper with active pistons both sides - I don't see the need maybe I'm missing something ?

ATTAK Z Posted June 1, 2010 Share Posted June 1, 2010 Copied and pasted from EBC website New disc pads take some time to bed down, even if you are using new or turned rotors and during this time when the pad is bedding in to match exactly the geometry of the rotor the pads can make noise. The normal way to minimise this is to add noise reduction shims onto the reverse side of the pads which dampens the vibration caused by the pad which will "Chatter" slightly when not seated perfectly. This noise would go away after 300-500 miles but to avoid irritation noise shims are used to reduce this sound. There is no safety issue when a pad makes these noises during bed in, it is merely a cosmetic problem of the new brakes. So I still don't see the necessity for shims to reduce brake squealing Quote Link to comment Share on other sites More sharing options...

They are OEM on the Brembo set up as they are glued to the rear of the front Brembo pad. that can't be classed as a shim then in the true sense of the word (pedantic I know .....sorry) they are an integral part of the (well designed) pad Wiiki says: "A shim is a thin and often tapered or wedged piece of material, used to fill small gaps or spaces between objects. Shims are typically used in order to support, adjust for better fit, or provide a level surface. Shims may also be used as spacers to fill gaps between parts subject to wear."
