Subpart #2 (of 340-04/240-04 - brake caliper) bumps into subpart #1 when brake pads are worn heavily:
If the outer pad is already screwed inward at full, the brake does not work and there is no way of adjusting it.
But it happens that brake pads are still usable at this moment - 5 minutes of ‘upgrading’ with a file and their life is slightly prolonged:
So, I just wanted to ask - is this a design flaw or is it intended?
left to right:
clarks MX2 organic pad
EBC MX2/MX3/sole sintered pad
hayes sole original pad
(I don’t have any semi-metallic pads)
Strida pad looks like organic.
To the caliper - the problem with the rear caliper was/is that it is not centered - outer pad was almost worn out, but the inner pad still had much meat on it. Guess I will have to chop some metal from the frame to adjust it.
Please don’t go chopping some metal on the brakes because it’s in the way just to save like $10 of brake pads at most. Because that piece of metal is there to prevent the brake cable from flexing too much when you pull and release. With that piece of metal gone it will be bent at a greater angle every time you brake and eventually it will snap on you when you really need it!!
every part on the strida was designed with a purpose I don’t think they went through 5 generations of changes to only keep that one part to make you buy new pads earlier.
Not sure if it is still actual but making lever go further than it suppoed to WILL result in brake caliper failure. Inside a caliper there is a piston. Piston is made out of two cylinders, one is has a notch preventing it prom turning, other turns freely. Between cylinders there are 3 metal balls that gave grooves that they sit in.Grooves have dynamic depth. When lever is pulled the turning cylinder spins and balls are pushed out of deeper grooves and made to go up to less deeper part of a groove. That pushes the piston that pushes the prake pad. If cylinder is turned too much balls fall out of their groves and braking mechanism fails. To repair it you have to take caliper apart and lace balls back to their grooves.
Hi Damian, I hope this photo helps, on a front caliper the bolt and washer should fit like this. The thick washer with the curve in it matches the curve on the caliper, this helps align the caliper to the plane of the brake disk when tightened. The small silver washer fits under the bolt head.
