Brake Ache

[wjw]

Finally got around to sorting out a replacement for front warped brake disc, 10" vented AP item, but was met with a pain in the wallet. £120+VAT each from Dartford.

 

Is there an alternative item??? since I only potter around country lanes, no racing and no track, ultimate performance is not so vital.

 

Thanks for wise words.

How did you manage to warp them just pottering about with no track use?

 

This is a serious question, since I've just upgraded from small brakes to big brakes, and I do a lot of track work and was under the impression that the big brakes were 'bulletproof'.

No they're unique

 

If you're serious about being a potterer and aren't really using the big brakes as they are intended, then if I were you I'd put an ad. in Wanted for the boggo brake set-up. You should be able to get everything from an upgrader for about £100 😬

 

Next you sell your big brake set-up to me for £120

 

Net result: you're happy, I'm happy and you're 20 squid in pocket

Brake discs do not warp in the simple sense - too much heat = bendy disc. Poor bedding in of the pads causes localised formation of cementite (form of cast iron). This provides an uneven surface wear and results in an uneven braking surface. If you don't bed you pads in right this will happen on any brake disc.

 

The AP discs are superb if treated properly.

Paul,

 

Like a lot of "potterers", I put on the AP big brakes to move the brake balance forward as I was constantly hitting rear-wheel lockup. While this phenomonen is fun when intentional, it is scary on a wet road when a car pulls out in front of you and you start to pirouette gracefully towards him!

 

Peter,

 

What is the correct bedding in procedure?

The uprated discs are made by ALCON not AP

I'm pretty sure my discs came in an AP box when I ordered the big brake upgrade kit from caterham last month.

Very interesting web page here. Also covers bedding in

Likewise when I ordered mine 10 years ago. Wouldn't be at all surprised though if they used Alcon to make discs to the same spec in the intervening time.
