First time poster here, i have a Merida 60D with tektro Auriga comp hydro discs.
I am looking for some help or assistance as i am thinking i should bleed my brakes soon and change the pads over. Looking on youtube (gotta love it!) looks like brake pads are fairly simple thing to change but bleeding them looks a little more complicated.
Can any provide any guidence on this such as:
Can i use other mineral fluid such as shimano in my tektro's? Is there any 'easy' way of doing this?
How do i get hold of a disc pad spacer..its like everyone would need one but no-one sells them?!
Any help or guidence would be greatly appreciated.
thanks in advance!
Any joy Matt?
I havent emailed the guy at this stage, i found some more stuff on the net which was simpler (ie didnt say i have to have my bike on a certain angle!) but i still would like like to know where to get a pad separator from and make sure the kits you can buy are the right ones to use, so i might email him when i have a chance!
Also on the ride, we ahve soemthing on at 11 so im thinking i wont be able to make it, definately up for it at a different time/day though!
is the Shimano fluid compatible with all the rubber and plastic parts/seals in the brakes?
Want cheap brake fluid try the auto section of a supermarket.
unless the brakes are spongy why would you need to bleed the brakes?
That is what i am not sure about, they are both mineral fluids but as to the compatibility i am not sure.
I dont really care too much about the price it seems though the shimano stuff is easier to come by and i wouldnt think that automotive brake fluid would be compatible with bike brakes given they are totally different types of fluids (car brake fluid being highly corrosive and all!)
The reason for me changing is just routine maintenance, you change the brake fluid in your car every so many km's or year(s) so why not bike brakes-my thoughts anyway...
If you're worried about bleeding them and oil compatability, flush the old oil out and replace with Shimano. If the brakes are working OK, I wouldn't worry about bleeding them, just replace pads. Bleeding is a simple process with the correct kit.
If you want the pad spacer, I have several and you can have one if you want to come out to Elizabeth. Most bikes come from the factory with the spacer to keep the pads in place until the wheel is fitted. Can't see why most bike shops wouldn't have some laying around in their workshop.
Thanks for the Help Gary, there is nothing wrong from what i can tell (i have only owned hydo's for the past 1-2 yrs!) so i think i will leave it for a while and just change the pads as you recommended.
As for coming to pick up a pad spacer i unfrotunately live at seaford rise and its a bit of a drive out to pick one up, thanks for the offer though.
One thing i have always wanted to know, is how hard are they to adjust, i used to have XT vbrakes and they grabbed with about a few mm of the level pull and i want that again with my hyro's but it seems that this is a bit more movement in them.
Any assistance would be appreciated. Also im tyhinking you own a shop, what one so if i ever need work done i can see if i can come down (up actually!)
My gut feeling (based on a bit of car experience)
1. If it ain't broke don't fix it.
2. Car brake fluid is subject to really harsh conditions - pressure, temperature well above boiling -that's why it has limited life. Bike brake fluid - much milder conditions, so may not need changing that often.
But if you do want to change it ... why not do it at Adelaide Communtiy Bicycle Workshop
They have books on bike maintenance, tools, and volunteer mechanics. Bring the parts and and fluid along - use the workshops tools - if you get stuck, the volunteers can help.
