Did I overcook my brakes? Bedding-in.

[fizzy_drink]

Err... I took the car for a bedding-in session.

Started gently... 50-30 gradual slow-downs... until I felt the pads starting to bite.

Cool-off for 15mins...

Then 80-60 a few times... getting harder all the time... cool down.

Then 3 consecutive 100-60.... (same as 80-0) cool down...

MY GOD they're good! Esp at higher speeds...

They're not as bitey at 30mph anymore... probably because the disc and pads are starting to take-shape.... or did I overcook it?

PS No smell of burning coming fron them at all... all I can smell is my new tyres.

ALL the above is in KM/h - so devide by 1.6 to get MPH ;-)

they will take 100 miles to bed in properly oms...

OH poo...

100 miles of start-stop-sart-stop... good fun I suppose.

Mintex:
M1144:
Clean discs with brake cleaner or other approved solvent. Fit your new Mintex C-Tech Racing Pads
Apply 2-3 light applications of the brakes at 30mph down to 0mph
Apply 3-4 steady applications of the brakes at 70mph down to 30mph
Leave as long as possible to cool down. They will now work from cold. Do not left foot brake.
M1155
Clean discs with brake cleaner or other approved solvent. Fit your new Mintex C-Tech Racing Pads
Apply 2-3 light applications of the brakes at 30mph down to 0mph
Apply 8-9 steady applications of the brakes at 90mph down 30mph
Leave as long as possible to cool down. They will now work from cold. Do not left foot brake.
M1166
Clean discs with brake cleaner or other approved solvent. Fit your new Mintex C-Tech racing pads
Apply 2-3 light applications of the brakes at 30mph down to 0mph
Apply 9-10 steady applications of the brakes at 90mph down to 30mph
Leave as long as possible to cool down. They will now work from cold. Do not left foot brake.
M1177

Apply 9-10 steady applications of the brakes at 90mph down to 30mph
Leave as long as possible to cool down. They will now work from cold. Do not left foot brake.
F Series
Perform 12-24 short hard stops. Stops should be done in low gear accelerating to high rpm before applying brakes in a short hard stub. Once a lower rpm is reached the driver should accelerate back to high rpm and repeat procedure 8-10 times. After this, drive a lap to test brakes, return to pits and let brakes cool before bleeding system.

Ferodo:
Perform 25-30 trial brake applications of 4 seconds each and using 50% of normal race pedal pressure. To shorten procedure, application can be made along straights as well as through bends. Then inspect surface of pads from the two hardest working wheels. The pads should show evidence of contact over the whole pads area but without glazing.

To optimise the performance and life of both pads and discs, during the above procedure heat in the braking system should be built up progressively. Brake pads should have at least 2mm of friction material or be replaced.

Pagid:
Perform 3-4 stops with light to medium brake pressure from 90mph to 65mph. Please allow 300-400 metres distance between each brake stop. The pads should not reach temperatures above 300-400 centigrade during bedding in.

Immediately after bedding in at high speed - one stop with medium to heavy brake pressure (without allowing brakes to lock) from 110mph to 65mph. 2-3 recovery stops with light brake pressure. Repeat the above up to twice including the recovery stops. Allow 500mm cooling off distance between high-speed stops. When mounting new pads on used discs, the edges of the pad surface should be filed 45 degrees to ensure that the pad carries fully and evenly and is not touching the edge of the disc.

Performance Friction:
Tape up ducts ½ - ¾. Make several slow stops to ensure sufficient pad/disc contact area (typically 80%).
Do not left foot brake. Do not drag brakes. Make several firm/hard stops from as high a speed as possible. These stops should be made early, as all pads will exhibit fade until fully conditioned. On light braking circuits extra stops on long straights can be made to speed bedding process. Continue procedure until fade is no longer apparent.
Important - make 1 or 2 cooling laps without using brakes.
Check temperature paints - discs must have reached peak operating temperatures to be sure of full bedding. Remove tape as required.
