Cleaning Disc Brakes

[Mr Haematocrit]

I don't think the issue is the amount of water being presented, I think it is the fact it is under pressure. Rain water is not under such pressure.

 

[grumpyoldgit]

I can make a pressure washer put less water on the bike than riding in rain can, which is why I have no problem using one. Others seem to think they are an item without adjustment, close up for some parts and a long way off for others.

Possibly so,& a surgeon can save lives with a scalpel,but the average person would most likely kill the subject.

So what you are saying is that it is not the tool, but the tool holding the tool. Which is a line I know I often have used on here.

Jet wash.

Probably not a good idea, for a couple of reasons. 1), it's difficult to jetwash discs without aiming pressurised water at the hub seals, and 2) you risk washing grease or oil from other parts of the bike onto the disc.

I've always used hot soapy water and a clean brush.

 

[screenman]

Do you guys never take your bikes out in the rain?

 

[grumpyoldgit]

Sure do,but it dont rain at 2500 psi round my way

I thought you were joking when you said jet wash...

 

[screenman]

A jet wash is no more powerful that a slight rain fall, when used correctly of course.

yeah,like when its turned off.There is an old saying

I give my brakes a squirt or Muc Off Disc brake cleaner every now and then. Seems to do the trick.

I got the pads and discs on my Magura brakes into a bit of a state through indiscriminate application of GT85.

A few squirts of Muc Off did a good job of knocking them back into shape.

I managed to 'borrow' the aerosol from the bike shop.

Ought to buy a tin, but it seems a waste for infrequent use on one relatively lightly used bike.

Like when you hold it way back from the object you are washing.

Seems to me I am not the one in the hole, do you want me to throw you a rope.

Or you could just leave your bike out in the rain.

If you hold it far enough away,it will have the same effect as a normal hose pipe.

So I see you are getting it now, in fact it can have less effect than a hose depending on lots of variations. Point being used properly it is a very versatile tools, for sure you would have problems getting thick clay etc, off of the tyre's, rims and parts of the frame as quickly and efficiently with just a sponge. Then of course you can back right away for the more delicate parts, should you wish to do so.

 

[grumpyoldgit]

Oh ,I get it,I spend a grand on a pressure washer,hold it far enough away so that I might as well have used a hose pipe in the first place,thus saving a grand
