Guidance On Bedding In Procedure

Geometric Alignment Of Pad Surface To Disc Surface (basic bedding in)

4-6 brake applications with medium pedal pressure from approx 90mph to 50mph, not allowing wheels to lock. (No brake dragging)

Allow for a distance of 300 - 400metres between brake applications for cooling period.

Pads should not reach temperatures above 400°C during initial bedding in. Check that pad
surfaces have at least 80% contact with disc before allowing more heat into pad surface.

Immediately followed by :

Bedding In At High Speed

1 brake application with medium to high pedal pressure from approx 110mph to 50mph
without allowing wheels to lock.

Allow 3-4 recovery brake applications with light pedal pressure.

Repeat high speed applications including recovery applications another 2-3 times.

Allow a cooling off distance of 500 metres between high speed applications.

I've found pagids a little tricky to bed in, for me it works to just use the car normally/gently for a few miles, and then follow the bedding in procedure.

Depending on how much pad transfer you have on your discs you may end up re-facing them, if you do then fit a new set of pads they will be perfect. Common cause of pad transfer is either keeping your foot on the brakes after using them at a junction or something like that or if the car stands for time outside water will sit between the pads and the discs and can result in the same effect, slight vibration when cool but terrible when hot and would need a re-face.

Hope that helps a little.

Hi All,

Big thanks for all the comments. As you can imagine I am not happy with the garage that put the new discs on - to now find they have put them on the wrong way round

Anyway I will get a set of Rs29's ordered first thing in the morn and get the discs off for a skim this week, then hopefully I will have some decent stopping power!

Cheers
Nick

Are my pf discs round the wrong way too?

**CraigMillwardCroft** · 19-07-2012, 12:45 PM

Going by the first thread on this subject yes if Performance Friction Disc's. What does there website tell you or install leaflet

Just checked and found a photo of mine, dunno if they've changed them since this though. All to do with the direction of the internal vanes, nothing to do with the direction of the grooves....

Hi All,

Well I had my discs changed round this morning so are now on the correct side. I have spoken to PF this week and sent them my pics and yep Phoenix - yours are on the wrong way round as were mine before today. Not sure if you have used your car since they have been fitted but if so then I spoke with the technical guy at PF this week.

He suggested the same as the advice given by the guys who responded to my original post, namely get them off, clean them up with light emery and swap them round, he said not to skim them and stressed this point, he then suggested a pad change and quoted some scary figures for the 01 pad compound

I elected to get them cleaned up as advised and put back on the car, retaining the RS14's. I left the garage and immediately did a rebed procedure on the pads. I am still getting a faint wobble when applying the brakes lightly but its a million times better than it was. I am going to do a few hundred miles and see if this resolves itself, if not then it will be a new set of pads. I know the RS29 is a popular choice and is an agressive pad so should help in further clean up of the disc. I have read the 01 gives off dust that can be corrosive to the wheel when wet so I think I will elect for the RS29's if the slight judder doesnt go.

Its a shame PF dont provide fitting instructions or stamp R/L on the discs to assist!

Anyway if my mistake helps others then thats something.

Cheers
Nick

Glad you got it sorted. I'm running pf discs with rs29 and it's a great combination.

How much did they quote for the 01 pads?

Nikey30 · 19-07-2012, 08:08 PM

£279 Plus Vat and carriage. I am out of touch with what pads cost so may get the same fright when I source the RS29s!

I did call Thorney Motorsport on Monday and spoke with a chap who said he would arrange for someone who could help to call me back, still waiting for the call

, so will be calling Simpsons when I am ready to order.
