Squeaky Mintex M1144's

[johnnyboy666 195 1 Cars]

Hello,

 

I've got some mintex M1144's in Peugeot Partner calipers, and they're noisey buggers. Light squeaking on gentle braking and a good old sing-song on medium braking, then quiet on heavy braking.

 

I last had m1144's in some 1.6gti calipers and they were a little bit squeakier than standard pads but not quite this bad.

 

Is there something I can do to tame the noise a bit?

 

The standard pads have a thin rubber backing on the pads, presumably to prevent squeaking, so I was thinking of getting some for these pads and see how that goes. Any other recommendations?

 

Cheers

 

P.s. I've checked the discs and pads for any contaminants and even wear and everything appears fine.

De glaze discs and pads with 36grit emery and try again

I presume you meant 360grit? Cheers, I'll give that a bash

[Tom Fenton 1,536]

No, 36 grit.

Did you follow the bed in procedure correctly?

I bought them with 500 miles already on them, so unfortunately not

May well be a contributing factor I'm afraid!

As Tom says give them a right good re-face and follow the bed in procedure.

I've thrown 1155s away in the past due to not bedding in properly.

I've found Mintex 1155 & 1166 to be very dependent on correct bedding in procedure, get it right and they are pretty good pads and even 1166 work well from cold temps but get it wrong and they are horrible.

This is the procedure for reference:

BEDDING IN MINTEX “F” TYPE MATERIAL

Follow the supplied bedding guidelines and not bedding procedures based on old technology. Failure to do so could result in brake components overheating and possible failure. Bedding Mintex F-Series material requires 12-24 short hard stops while gradually building temperature. To do this without overtaxing the system, the stops should be done in low gear to ensure that the energy input is limited. Accelerate to a high RPM level and apply the brakes in a short hard snub. Once a pre-determined lower RPM level is reached the driver should accelerate back to the high RPM immediately and repeat the procedure a further 8-10 times.

After this a lap can be driven to test the brakes. If necessary the entire process can be repeated to give a better feel. On returning to the pits the brakes should be allowed time to cool and the system bled before further use. It is stressed that when carrying out the bedding process, the brakes are not dragged or the car taken from very high speed to very low or a stop. To do so many results in damage to or failure of brake system.

BEDDING IN MINTEX “M” TYPE MATERIAL
M1144 / M1155 / M1166 / M1177

1. Clean discs with brake cleaner or other solvent.
2. Apply 3 to 4 light applications of the brake from 30mph down to 0mph
then......
M1144: 6 / 7 steady applications 70mph down to 30mph
M1155: 8 / 9 steady applications 90mph down to 30mph
M1166: 9 / 10 steady applications 90mph down to 30mph
M1177: 9 / 10 steady applications 90mph down to 30mph

FINALLY.... Leave to cool as long as possible ( They now work from cold )
NOTE: DONT LEFT FOOT BRAKE ! & DONT LOCK-UP THE BRAKES !

Cheers, reface and bed in it is then. Looks like a 3am dual carriageway run might be required for the bedding in procedure!
