FAQ - Brakes - READ ME FIRST - Updates 9/04!
#494899 - 01/05/04 10:54 PM

FYI! The FAQ is a work in progress and roughly applies to the entire Contour.org Community, please be aware some vehicles will be different do to a factory quarks or aftermarket modifications!

Please reply if you see spelling errors, have info to add, or my words are unclear! If anyone wishes to use or link to this FAQ, please PM me.

Braking Facts/Ideals:
-------------------------------------------
What brake pads are the best?
This is too broad of a question. What kind of performance are you looking for track or street? The quality of pads also varries, some have great experience with a certain pad while others have a horrible one. Search the forum for a specific pad name and you should get plenty of opinions.

Brake pad bedding!
Brake pad bedding is the process of mating your pads to the rotors. Most pad manufacturers have their own procedures as do most car web sites. Some are good, while others encourage you to grossly exceed safe driving speeds. The best I can tell you is to avoid emergency stops for about a five hundred miles. Also, I suggest you preform some smooth high speed to low speed agressive slow downs, using threshold breaking*. This will help bed the pads to the rotors. It is also not good practice to park your car for a long period after over heating your brakes and rotors. This can contribute to warping. Drive around until they are back within normal braking temps before you park.
*Threshold breaking is agressive breaking without the use of ABS. In other words, you are brekaing hard on the threshold of using ABS but are not engaging it.

What are the benefits of cross-drilled/slotted rotors?
The simple answer is asthetics! Slotted and cross-drilled rotors do not improve braking nor is the weight savings beneficial. Often, the slots and holes cause quicker pad wear and shorter rotor life due to cracking and warping. You've heard that the unspring weight savings can help greatly, false. It is beneficial on a vehicle as weight sensative as a motor cylce but not on a street car like the a Contour. Your best bet for good braking and pad/rotor life is a quality set of blanks!

What are the differences in braking fluids?
Here is an old but very thurough brake fluid breakdown. My personal choice for performance vs cost is either ATE fluid. FYI, the fluids with higher boiling points usually absorb moisture quicker causing a spoungy pedal, requiring them to be flushed more frequently, i.e. once a year. The lower boiling point fluids can usually last two years.

What are the advantages of Stainless Steel brake lines?
Stainless Steel(SS) brake lines primary benefit is pedal feel. They don't stretch as much, if at all, as rubber lines when under pressure, giving the pedal a stiffer feel. Asthetically they are pleasing. The weakness with SS brake lines is where the braided line attaches to the coupling, if the line is bent at this point the line is likely to break or spring a leak. As such, they come in two types DOT approved and track only. DOT approved lines have plastic protectors around the braided line as it attaches to the coupling, reducing the likely hood of a failure.

What are the differences in stock front braking systems?
Calipers types(two types):
-Type A calipers are on all Contiques, Cougars, and late model SVT Contours. The pads for these calipers are thin and long compared to Type B. This caliper has two mounting brakets, one for 260mm rotors and one for 278mm rotors.
-Type B calipers are only on early model SVT Contours. The pads for these calipers are shorter and wider than Type A.
* The date in which SVT Contours switched from Type B to Type A is unclear. Some say early in the '99 MY others say in late 98.5 MY and evidence suggests it wasn't quite clear to Ford either. The best way to find out is by comparing your pads to the pics in the http://www.batinc.net Contour/Cougar catalogue.
** Which Type is better has been debated but no hard evidence has settled the dispute. Type A has a greater swept area while Type B physically covers more of the rotor. Type A does have a better pad selection.

Rotor types(two sizes):
-260mm rotors are standard on all non SVT Contiques and Cougars.
-278mm rotors are standard on all SVT Contours and an optio on some Cougars.
* I believe the distinction for Cougars is realted to what engine and if the car came with Anti-lock brakes. i.e. If you got a V6 with ABS you have 278mm rotors, if not you got 260mm. Maybe a cougar expert could post the right info for me.

What are the differences in stock rear braking systems?
All four wheel disk brake Contique and Cougars have the same rear disc brakes! Rear drum equipped 1995-96 cars are equipped with 203 x 38mm (8") rear drums, but 1997-2001 cars are a mix of the 203 x 38mm (8") and larger 228 x 45mm (9") drums. This is probaibly a manufacturing supply issue when the cars were built and the only way to determine which rear drum/shoe set is on you car is to check before ordering parts. Conversion from drum to disk is possible and has been done several times. Check the other stickied posts.

While braking, you feel a pulsation or strong vibration in the pedal.
-Most often, this is cause by warped rotors. You can either replace the rotors or have them turned. If you just recently had new rotors installed, turn them. If you are at the end of your pad cycle, get new ones.
-But that is not always the case. Rotors are know to have pad build-up which can cause puslation. This link contains information on brake pad build-up and other usefull braking facts.

When you push the brake pedal at a stop or while braking it feels soft and/or spoungy
-If the problem occurs suddenly after a brake job, it is most likely caused by improper installation of the front caliper retainer springs. If they are not install properly your brake pedal will feel weak.
-If the problem occurs after caliper replacement or brake fluid flush, it is likely caused by air in the brake master cylinder or brake lines. Air in the lines can be solved with a simple bleeding of the hydrolic system, see below. Air in the master cylinder, is a big problem that is best handled by a professional with special tools!
-Otherwise, it is likely due to moisture in your brake fluid. Most commonly a simple brake fluid flush will fix it. See the Brake Fluid Flush/Replacement: Pedal Pumping Style! in the How To section of the Mods/Parts page of the main site. With DOT 3 fluid you can replace it about every 4 years. With DOT 4 fluid you shoudl change it every two. Good maintenance practice would be once a year. It's cheap and easy.

How much time or money should it take to install ____?
Install time depends on experience and cost depends on labor rate. Specifics can best be found by searching, looking at the Ford repair CD's, or talking with members in your local forum. Often, another member is willing to help or knows a shop that can get it done at a reasonable price!

OEM Replacement brake pad and rotor options:Below are links to two companys and Stazi, which provide pad and rotor options to CEGers. Others do exsist these are just the most commonly used with good service.
Stazi's brake supply information!
BAT Inc Catalogue!
SP Motorsports Contour brake options.

Stazi's Bendix Titanium Metallic pads and Autospecialty Rotors are a popular choice amoung CEGers. Good performance and an even better value for the mildly aggressive driver.

BAT and SP Motorsports offer a wide array of pad types , track and street, and rotors at a wide array of prices.

Front Brake upgrade options:
WilWood Caliper based front brake kits!
Check out TCE Performance!
TCE offers 12" and 13" rotor options and four different styles of Wilwood calipers, including FSL, BSL6, DP, and NDL.

BAT Inc. offers Wilwood Kits as well!
BAT offers Wilwood 4-Piston calipers and mounting hardware for stock 268mm rotors and 300mm rotor.

SP Motorsports resells both BAT and TCE brake kits.

For the rear, they offer a kit includes; hats, 11.75" rotors, brackets and hoses to enlarge rear brakes using the stock calipers. This will retain the parking brake, greater braking power, and it will compliment those 19's nicely.

Baer Caliper based front brake kits!
SP Motorsports sells Baer kits.

CTA Motorsports also offers a wide variety of brake parts for the CDW27 platform.

The sites listed above are not the only sites that provide us with brake upgrades, but they are commonly used by CEGers.

To clarify the Cougar front disc info.

278mm rotors came on all "Sport Package" equipped Cougar's. This also included 16" chrome wheels, fog lights, spoiler, and removed speed limiter. There were other parts on it, but those don't pertain to the brakes question.

260mm rotors came on all NON-Sport Package Cougar's, easily seen by having the 15" fanblade rims.
