Glazed brake shoes
« on: 21 September 2010, 18:57:37 »

I am a very light brake user, and suffer glazed brakes shoes on the motorbike.
I am a bit fed up of changing just because they are glazed over.

Was wondering if ok to attack them with a bit of course sandpaper or something.

Thanks for your advice.

I've heard of using sand paper on new shoes to help them bed in, don't see why you couldn't do the same to remove the glazing as long as you sand the whole surface evenly...

Deglaze with a file is what I was told.
Done quite a few on trucks in my time.

To be honest, every time I glaze them up, it doesn't matter how much I file off, I can never get the same 'bite' back, so I tend to replace them...

This is only on Omegas, been a long time since I badly glazed up the Rover or Kawasaki...

Does that mean you 'brake' on the gearbox so the poor buggers behind have to guess when you're slowing down?  ::)  ::)  ::)   ;)

Like we were taught to ::)


Mind you, for me, the engine doesn't provide anywhere near enough braking ;D

Taught? My 'lessons' were ...... there's the brakes, there's the clutch ..... off you go!  :y  :y  :y  :y

Seriously, I drew the short straw on a road run behind a clown in a diseasal modern-ish 'micro car' ...... forgotten what make ..... and the driver just wouldn't use his brakes. I even questioned whether his brake lights worked, his reply 'I never use the brakes'  :o  :o  :o Even when I suggested it might be a good idea for  those behind him ie ME, he still wouldn't use them!!

How do you end up with glazed brake shoes? Thanks

Brake pads are cheaper than gearboxes.....  We were taught (at advanced driving level) to use either the brake pedal or the clutch pedal singly i.e. either one or the other.  You are either braking or changing gear, never both at the same time.

Do all your braking with the brakes to achieve the correct roadspeed desired then block change to the suitable gear to drive on with.

Still do, to a certain extent, with the autobox.  Brake off the speed in a oner, then drive onwards as required rather than brakes on/off/on/off/on/off.....

And at the original poster, glazed brakes are easy to achieve if you brake too lightly and often.  Sometimes can be rejuvinated by a healthy brake from speed two or three times to wear off the glazed surface but file/emery also works.  Unless the pads are reallt cooked and then replacement is the only option.

remember to free and clean off the pistons/calipers/landing faces properly and use coppaslip or similar sparingly to reduce squeeling.  (NOT on the pad to disc face, obviously....)   :y

Totally agree, for all vehicles with modern brakes.

The "older" technique of engine braking was based on the fact that old drum brakes were highly inefficient at any speed, tended to overheat very rapidly when used at high speeds, and were, comparatively, expensive and time consuming to replace.

The technique mentioned of either brake or clutch, never both, is mandatory for all LGV/PSV driving ... breaking ( :)  ) that rule is an instant fail of the test. (Obviously for the pedants .. you do brake and clutch together as you come to a halt .. but under normal driving it is a no-no....  :) )

Hence the use of 'sustained rev' gearchanges where very slight depression of the accelerator increased the revs when the clutch was depressed such that when the clutch/lower gear was re-engaged, the change in passenger comfort was seamless and there were no nodding donkey impersonations from the passengers as revs were brought up suddenly from tickover to a handfull of thousand at an instant....   ;D

Thanks guys
By "light braker" I mean I try to read the road ahead as much as possible, and adjust my speed accordingly. Hence I rarely ever need to apply the brakes hard.

There is one road on my commute journey which is 3 miles long and very twisty, with care you do not need to touch the brakes at all, I have a small game of counting how many times the vehicle in front brakes on this road. The average is 6, but the highest record so far is 43 times.  :o

Oh yes and I don't hold people up driving this way. In fact the speed then brake hard people do more to cause hold up problems.
