Rubber Posted May 19, 2011 Share Posted May 19, 2011 I had what felt like a warped disc when braking. Brakes were working ok but you could feel the brake slightly pulse when stopping at low speeds. I changed the pads all round for Ferodo DS2500 a couple of months ago. The old pads were a disgrace. I intially though the brakes were better following the change but the pulsing was still there. So, on to Zmanalex again for a new set of front rotors. Removing the old rotors and the spacers This is what the old rotors looked like when they came off... Don't look too bad really. But wait, thats only the visible side of the rotors. The engine side looked like this To be honest I'm not experienced with performing car maintenance myself. However, my father in law is a helicopter mechanic and he's worked on cars all his life so under his guidance things are a doddle. Plus he has a tool for every occassion! To remove the rotors we: 1) Removed the wheel nuts 2) Removed the wheel spacer (get another person to step on the brake pedal when undoing the nuts for this one) 3) Unbolted the two large bolts holding the brake caliper in place 4) Slowly pushed the caliper off the rotor (making sure we did not bend the hard brake pipe too much). Then remove the rotor which comes straight off. The hard brake pipe is shown in this pic. We could have removed the bracket (black) for the brake pipe but we thought it would be easier to leave it in place. Not sure if other people do it this way? 5) Bolted the caliper back in position to support it while we cleaned up the hub. We used a drill with a wire brush type attachment and some scotch brite to clean up the hub. Also took the opportunity to spray anti-corrosion agent around the brake pipes etc. 6) Removed the bolt supporting the brake caliper, slid the rotor into place and bolted everything up. (Should have mentioned that we cleaned the rotor with brake cleaner to remove any anti-corrosion agents before installing the rotor.) Then went though the brake bedding in procedure as per the Stoptech guide in the Guides section. Brakes feel a lot better and the low speed stopping judder appears to have gone away. So, to sum up: - This job is very straight forward and you only need basic tools. This total job took about 1 hour. Best to have two people though to get someone to stand on the brake and also when removing the caliper - Check the condition of the inside of your discs. You can feel them with your hand through the wheel but probaly best to get the wheel off and get your head right in the arch to visually inspect. FYI - my car is a 30,000 53 plate so not a huge amount of mileage but the car is relatively old. Thanks to Alex for the new rotors Cheers, Chris Quote Link to comment Share on other sites More sharing options...
rabbitstew Posted May 19, 2011 Share Posted May 19, 2011 nice guide! i`ll be doing this on mine soon and am thinking about the same choice of rotars / pads. Quote Link to comment Share on other sites More sharing options...
James B Posted May 19, 2011 Share Posted May 19, 2011 What rotors did you have before? Quote Link to comment Share on other sites More sharing options...
Rubber Posted May 19, 2011 Author Share Posted May 19, 2011 What rotors did you have before? I assume they are the OEM rotors for the GT. I got the car 3 years ago with only 16,000 miles so I assume the pads and rotors had never been changed. Chris Quote Link to comment Share on other sites More sharing options...
Blacky Posted May 19, 2011 Share Posted May 19, 2011 " RIGHT THAT'S IT" ...............................WTF ARE ROTORS? If you mean your discs, then they look very good write up and pics. Just cut it out with the "ROTORS" Quote Link to comment Share on other sites More sharing options...
Rubber Posted May 19, 2011 Author Share Posted May 19, 2011 " RIGHT THAT'S IT" ...............................WTF ARE ROTORS? These are rotors...http://www.350z-uk.com/forum/viewtopic.php?f=157&t=46541. Just like it says on the box To be honest I wasn't even aware I was calling them 'rotors'! I would have always called them 'discs' in the past but I must have been converted by my research on the forum. A search will reveal that both terms are used. Not sure if there is technically a difference? Is rotor what the Americans call it? Quote Link to comment Share on other sites More sharing options...

Watshot Posted May 19, 2011 Share Posted May 19, 2011 'Rotors' is the American term for brake discs. The same as in the U.K we don't say 'trunk' when we mean 'boot', or 'fender' when we mean 'wing'. And whilst we're at it it's spelt: Brake, not break. Disc, not disk. That's one that has bled through from the eighties computer industry: 'floppy disk'. Good. Carry on.

evilscorp Posted May 19, 2011 Share Posted May 19, 2011 Will be doing mine soon, just waiting on my new low trolley jack to get the dam thing up Have you put new ferodo pads on too? how much difference over oem parts Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted May 19, 2011 Share Posted May 19, 2011 Great write up Chris And well done for taking on the brake upgrade yourselves. However, so happy that you did not tell the full story Alex. Quote Link to comment Share on other sites More sharing options...
Rubber Posted May 19, 2011 Author Share Posted May 19, 2011 Will be doing mine soon, just waiting on my new low trolley jack to get the dam thing up Have you put new ferodo pads on too? how much difference over oem parts Can't really tell you how much an improvement it has made because my discs and pads were in such a bad state In my particular case it is a big improvement. Alex - the slight detour to Clarke Motorsport was an eye opener! They had a load of nice cars knocking around in the car park, R33, Impreza, Evo etc. Inside the workshop was spotless. They had a few other interesting projects inside including a stripped out DC5 in progress They were servicing an Impreza at the time as well so they do work for us ordinary folk as well!!! For those in Aberdeen they are located in Kintore and may be worth a look....http://www.clarkmotorsport.co.uk/website/index.asp?refID=1&pageType=C Quote Link to comment Share on other sites More sharing options...

Rubber Posted May 20, 2011 Author Share Posted May 20, 2011 Wouldn't they have failed an MOT? Ha ha! You would think! The garage passed them but put an advisory that they shold be changed. Quote Link to comment Share on other sites More sharing options...
