    Couple of stupid questions but hey....

    srry guys this is probably a pretty stupid question but, what is the difference between mechanical disk brakes and hydraulic disk brakes? What are the pluses and minuses?

    Also what is the little cylider above some rear shocks? What does it do and how does it help?

    mechanicals: cheaper, use standard levers and cables so repair is easier
    hydrolics: better feel, better modulation/power (depending on system)...if you put a premium of braking performance, these are what you get

    that reservoir on the shock is called a piggyback (ones that are detached are called remote reservoirs). Its a chamber that allows the oil to be displaced by the shock piston through the stroke (ie. the chamber has a piston that seperates the oil and air pressure). It also can introduce some damping functions to the shock depending on the design.

    Also hydraulics generally require less maintainance once setup properly.

    Turns out that five years of not mountain biking, really makes one strive to get back to it.

    what are you referring to?

    Your avatar or disc brakes?

    Well set up mechs can be pretty smooth.

    you also do not have to worry about the cables stretching on hydraulic, but if you squeze the lever with no front wheel on it screws them up and is a pain to fix. it is because they are self adjusting

    It also might help to know that hydraulic brakes use hoses and fluid.( hense the name "hydro") Sometimes this can cause problems like leeks and air in the system.Generaly hydaulics are better and more energy efficient tho.

    Hydros; Less maint, better feel, better heat dissapation (less fade), my hydro pads don't seem to wear down nearly as fast as mech ones (most likely due to the heat dissapation).

    Mechs; Cheaper.

    Those are the advantages of each. All other catagories are debatable untill the cows come home (like which is easier to set up, and I know examples of both that are easy and hard).
    I know in my heart that Ellsworth bikes are more durable by as much as double. AND they are all lighter...Tony Ellsworth

    another advantage for mechs - more adjustable. They may be making strides w/ the Juicy and El Camino, but still no hydro offers power/ modulation and lever pull adjustments.

    well just about every hydro has a lever adjustment at least. As for the power/mod adj., not all that usefull IMO...i just want the most power and i'll get used to modulating it. And not much of an advantage if hydros have more power anyways.

    hydros have lever reach, but not pad engagement point adjustments. And from what I've heard, the power advantage is debatable. I haven't owned a set of hydros (altho I've worked on them a fair amount) and I won't rule out owning a set on my new bike, but they will have to kick ass and not cost and arm and a leg...

    Used hydros is where it's at.... I mean other than a bleed and maybe a new set of pads, as long as its in working order its all good.

    but also very real. For one thing, brake fluid isnt compressible, but brake cable lines do stretch. Then theres the heating/brake fade issue.

    when was the last time you saw a car with mech brakes?

    that's what 8" rotors are for

    I'm 190 w/o gear, haven't noticed fade with my 8" fr/ 7" rr Avid mechs downhilling all day at Keystone, Vail, WP. I can't say as I've ever felt the need for more power, either. Maybe I'm not dragging my brakes enough?
    You're not going to get cable stretch unless you are at a mechanical disadvantage and have to really torque on the levers. Due to the leverage they provide, I can brake w/ one finger, and I don't think I'm strong enough to stretch a cable with one finger. If cable stretch does occur, it only is a finite amount, and is easily adjustable, not that I've ever noticed or had to adjust for it.

    Also never seen a 40 lb car.
