Valve clearances are free, so you can't moan about the cost of that!!!!

If I had enough money to not have to moan about spending it, I probably wouldn't have bought a Skoda !

i just changed the shoes on my drum brakes, and i need to change the disk and the right shoes on my front and found a `couple of problems but easy to solve;

the brake are auto adjusting, but the spring doesnt have the strenght to move the pin due to dust rust and etc... i just cleaned everything and greased the pin

the brake have a lot of travel before meeting the pads and the spring inside is not strong enough to keep them together before pumping so i streched the pring a little

if misture gets inside the brake cilinder i glues it with rust so i cleaned it and removed the rust, applied a fair amount of axel grease to lubricate and inside the dust cap to waterproof.

i sanded the cilinder with mild sandpaper to remove the rim of rust (where the shoe doesnt meet) to make it easier to fit back and also to make a better contact suface (sometimes heat and presure make the brake crystalize and afterward they dont grip as much and they feel as they slide, making more heat and futher crystalizing watever residue is there)

installed the drums back and operated the hand brake 4 to 6 times to let the pin settle and then i bleed the foot brake first the right wheel then the left making sure all the bubbles where out

now brak travel is 1/2 or even less that it was before, handbrake grip is good and it only travel (with force) to the first mark, when i press the pedal in afraid of locking the wheel since a couple of times i felt like i was going to be lifted from my seat due to exesive braking (still have to get used to it)

so do check the servo, and master cilinder, do check rear drum brakes make sure the little pistons are not locked with rust (meaning your using 2 instead of 4 wheels to brake) and do check youre using the correct braking fluid (DOT 4 if i´m not mistaking)
