Best way to bed in brakes?

[Adam318i]

Right, well i big thanks to Steve (zone name mtec123) and fred who fitted all my brakes for me, top BMW garage

Now hows the best way going about bedding them in?





Also got the 325 rear ARB on aswell

Oh and that little ding is now sorted,

drive up to about 30 or 40 then break very hard, then accelerate, then break hard, try to do this on an emoty bit oof road though

then try slighty higher speeds of about 50-60.

should be ok after a few go's of each.


thats how i would do it anyway

[TOURINGDADDY]

just take it easy mate 150/200 miles is good adn don't keep foot on brake peddle once u have stopped

[TOURINGDADDY]

billgatese30 way will only glaze the discs and pads which is bad

[johnono]

id drive nice and gentle for about 100 miles, til the first skin is worn away on the pads and discs.

dont be hittin the brakes hard or the pads may begin to wear uneven or mabey even score into the discs

[Nostrils]

I also advice to take it easy for the next 100/150 miles without too much sharp braking!

[billgatese30]

oh well...thank christ i haven't got any new brake pads then

can't remember exactly where i learnt that info from now but i know that whoever it was was a bloody liar


just hope you haven't gone out already and started jamming the brakes on left right and centre

I am a former Brake fitter and if you do it this way expect to replace them within a couple of months!!!
As Touringdaddy said, you will glaze them and it will make your stopping power even worse! The pads will crack after a matter of time and then break away and it will be metal on metal which means back to the garage and more money spent
Just take it easy for first 200 hundred miles with light braking and brake well before you normally do otherwise you will end up in someones boot.

Cheers,

I remember this topic came up a while back, and there was a link where it also said the best way was to give some good sharp stops from a good speed, and it was tried and tested to a great result.

Personally I've always used the take your time method, but I remember when I was younger my dad always used to use the sharp stop method, and his brakes were awesome, and he never had any problems!

Slightly off topic but sort of relevant!

A mate of mine changed a clutch in his Cortina Mark IV after work and finished about 9:00pm. He pulled up at the corner of the street where the gang were hanging out.

I told him to be careful with the clutch being new, let it bed in.....he was a practising mechanic and just said, no worries should be alright.

He wound the window up, revved it high and dumped the clutch.....smoke started, big grin on his face thinking he was doing a burnt out.....we had even bigger grins and pointing under the front of the car, then suddenly a chunk of clutch came flying out of the inspection window....

...guess what he was doing the next evening.....and all on a side jack!

There is a moral behind that story somewhere!

thats probably where i got the idea from, was on the old zone i think

[Karan]

depends what pads u r running.....

if ure running race stuff... bed in is different...

[Adam318i]

Yea thats where i remember how to bed them in but didnt really want to cain them without being sure first.

I think im just gona take it easy on them for 200 miles

Ta guys,

if u have new disks u need to take it easy for 150 to 200 miles. Thats what ATE say to do with your disks. U don't want to warp them mate

With fast road/competition pads they usually say the sharp stop routine from different speeds and holding the pedal for say 4 secs with the pedal half pressed

[astondg]

I got some new pads fitted the morning of the day before I went to track day, unfortunately I had no choice. I took it easy on the drive home from getting them fitted, about 50 miles. Then I did some medium braking from about 50mph to 30mph and then 60mph to about 30 to 35mph. Then on the way to the track the next day I took it easy until I was almost there, about another 50 miles, and then did some more braking from similar speeds with about 3/4 pedal pressure. Then I was on the track and used about 3/4 pressure for the first few laps and took it easy for a couple to let them cool. By the end of the day I was breaking at or very close to maximum, although with the spongyness of the brake pedal I can never get to full braking on bitumen and I never locked a wheel.

They seem to be ok so far, not sure how they will be in the future.

well, a candle lit dinner and dancing on a beach usually works for me...


OH sh!t, you mean bedding IN brakes??

200 gentle miles with granny braking all round

[orangecurry]

it just so happens I had some M1144 pads fitted yesterday, and here is what Mintex recommend in a handy-sized leaflet:

"1) apply 2 - 3 light applications of the brakes at 30mph down to 0mph

2) apply 3 - 4 steady applications of the brakes at 70mph down to 30mph

3) leave as long as possible to cool down. They will now work from cold.

DO NOT LEFT FOOT BRAKE"
(pfffft borrrrrrING)

but as Karan said, comp pads will be different; I know it's dull, but read the documentation on your own pads BEFORE you enter the Indy 500

[Bob_S]

use them as normal well if your a heavy braker use them lighter for about 200 miles. also dont stop the car on them entirely otherwise you will leave pad deposits on the disc and this will give the disk a warped feel and time for new discs

Thats how I do mine on my pagid 42s, I've bedded in brakes that I have fitted trackside with a few gentle laps before and never had a problem
