Q. What you will need to change your brakes & rotors on the 2006 Rendezvous


A. First of all, its not that hard to do, so save yourself hundreds by reserving a Sunday to do it yourself. For the rear brakes you'll need an 18 mm and a 14 mm box wrenchs. For the front you'll need a 15 mm and a 12 mm. Plus you'll need a lug nut wrench 19 mm. You should also pick up some silcon (not litium) based grease for back caliper screws on the back axel. Nothing is needed for the front.


Now if this is the first time that you're changing the brakes/rotors be prepared that the 15 mm screws on the front brakes require Herculean forces to remove due to the red lock-tite that they come with from the factory. Speaking of, I recomend picking up some blue locktite to replace it with. To remove the 15 mm screws you'll need a pipe or second wrench to increase your applied torque.


Ignore the webpages that say 30 minutes per tire... I can't imagine doing it that fast unless you have pneumatic tools (which aren't necessary). Just some elbow grease and about 1 hour per tire assuming you're jacking up the two tires at a time: front than the rear or vice versa.


As for the actual parts, head to rockauto.com I got 4 rotors and a complete set of brake pads for ~$200. I recommend going with the daily driver sets instead of the economy.


Parts list:

- Jack 2-ton ($25 at Walmart)

- Jack stands ($25 at walmart)

- Wrenches (12, 14, 15 and 18 mm)

- Lug nut Wrench (19 mm)

- Blue lock-tite

- Pad and Rotors from www.Rockauto.com

Q. How the hell do I write a matlab text file with a header?

A.
filename = [filename '_back.txt']
fid = fopen(filename,'w+')
header = ['m4, m1, m2, m3, m5']
fprintf(fid,'%s\n',header)
fclose(fid);

The trick is the %s which writes a string instead of just one character at a time.. otherwise you'll end up with comma's between every letter. There goes two hours of my life :(
