I got someone to help me test the brakes on my car and he pointed out that they don't seem to respond as well as his GTS, given that his car is lighter I expect my car to give up a few inches.

However it seems that my brakes really doesn't brake as well as his. I've checked my pads and they look fine, as with the rotors.

What seems to be the problem? I've known about the brakes since I got the car 6 years ago and thought this was normal.

you have a GTR. ie you have a front wheels with driveshafts in them. its nose heavy compared to a lighter GTS as you have an extra turbo, heavier hubs and suspension etc. an extra diff in the engine, driveshafts, an ABS system etc etc.

hehe. I think he knows the GTR will "give up a few inches" due to weight, but has it been compared to another GTR?

( I would still cover the basics, if it has shit pads from a RWC such as bendix advance in it it won't stop for shit for example.)

Little things like the age of the rubber brakeline hoses (older hose will "stretch" and relieve some of the braking pressure) and firewall flex (relieving pressure applied from the pedal to the master cylinder) can have an effect on braking efficiency.

Thanks. I'll get those checked out.

RB_ryan, all stock. When I slam on the brakes there's no skidding or sense of urgency. It could be the hoses or something other than the brake pads and rotors themselves.

I assume you've already changed the brake fluid and bled the calipers (which is the best place to start), but have you bled the ABS? You need a vacuum pump to do it.

Second step is getting pads with higher co-efficient of friction.

I am running gtr brakes in my bunky, so carrying a weight penalty over and above what a gtr has even (all steel front panels).. Recently rebuilt the whole lot with new discs, good pads, rebuilt m/c and good fluid. Stops awesome.

MrKotter, you don't need a vacuum pump, I did the whole lot with one of those one man bleeder kits, ie, tube in a little bottle.

Heller how does that work with the ABS higher than the reservoir? I ended up shelling out for a hand pump to do mine after replacing the ABS.

I hooked the hose on the fittin, opened it up a bit and then pumped the pedal until I could see the fluid clear with no bubbles.. went and closed it off, went to the next fitting and rinse and repeat.

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
