disc brake dilemma??????

[02GF74]

hmmm, I now have disc brakes made by Shimano, Hope and Magura

The Magura reservoir cover says use Magura mineral oil - is this the same as the red Shimano oil? A quick search on Chain Reaction seems to say yes. There are 2 types of fluid - mineral (shimano & magura) and DOT (car brake fluid).

(Hope is sensible as it uses car brake fluid).

I don't want to keep spares for 3 different makes, in fact don't want 2 makes but the Magura's are very sexy B) so I'll keep them. Keeping to one model means I need to get one set of pads, one type of oil, hose olive, rotors etc.

Should I replace the Hope - think they are M4 with Shimano 4 pots?

Generally Hopes are meant to be the bees knees, they are nice and effective but I am not sure thay are that much better than the 4 pots.

What to do ..... ?

I got two kinds, avid and Shimano SLX and its a pain, as you need to keep parts for both.

I'm replacing the avids with SLX when they give up purely for the sensibility of having one kind and only one set of spares B)

Which will take the paint off anything it touches! Very sensible.

On a bike's brakes I doubt that getting the grade of oil wrong by a little bit would make much of a difference. If it's too thin it might get past the seals, but I doubt it.

Oh, PS Mr Austin. Do your Shimano brakes squeal like blazes?

Mine do. I've just tried some copper grease on the back of the pads but I haven't tried the bike out yet to see if it has worked. Not an ideal solution though, because of the risk of the grease getting washed down onto the disc, but if it works I can look for a better solution.

It isn't as dramatic as that - you just need to keep a cloth and solvent handy. My many cackhanded accidents have never actually resulted in paint damage to a bike. I've a few marks on my tool box and workstand from splashes that have been left overnight.

 

[Mr Pig]

Yes, but it would be dead easy to miss a drip on your frame. And why use it when mineral oil works just as well?

Get the odd squeal in the wet, but nothing really bad.

Mine are horrendous!

Get a different brand/compound of pad it may work?

Get a different brand/compound of pad

I'm planning to, but I'm too tight to bin perfectly good brake material ;0) When I bought the bike I found what looked like brake oil on both of the disks. I checked the system for leaks and took it back to the shop and got them fit new pads and clean the disks. I hoped the brakes would settle down and be quieter after bedding in but they never have.

Personally I think it's a less than ideal design and some anti-rattle shims or compound should sort it. The problem is that you've not got a lot of space to play with.
