Sajeev,

Second time caller, long time fan. I have a 2009 Civic EX five-speed sedan I bought about 18 months ago and am hoping to drive into dust. I bought it instead of the Si because the EX gets slightly better gas mileage, uses regular gas instead of premium, and isn’t as … extreme?

Yet, naturally, I threw all the EX’s comfort out the window and let my inner ricer take over.

Greetings,

Another longtime listener, firsttime caller … I have a two-parter.

First: My 2007 Nissan Frontier will soon be due for a rear brake job. I’ve never worked on rear disks. Should I replace the emergency-brake shoes as well as the service brake pads, or will a simple inspection of them do for now? Also, I’ve had varying advice here: should I have the rotors turned, replaced or simply let them be if no pitting or warping is detected?

Second: Last year, my father and I replaced the U-joints on the prop shaft and since that day there’s a vibration around 55-60 mph. Whether I’m in 4th, 5th or 6th gear is irrelevant and the vibration goes away above and below that range. I do remember when trying to remove the old U-joints, my father took a small chunk, maybe a half-inch square area, out of the shaft right at one of the ends, and I’m pretty sure this is causing it, but is there anything I can do about it?

Sajeev,

I am probably the first owner of a Civic Si to ever want to downsize his rims, so I’m looking to the expert on -1 matters: you. (Woot! –SM)

I have a 2007 Honda Civic Si sedan with the factory 17-inch wheels. I’ve always preferred the same generation EX’s 16-inch five spoke rims, and I wouldn’t mind a smoother ride and cheaper replacement tires if I still get decent handling performance out of the 16s.

Would the 16-inch rims fit around the brakes on the Si and otherwise safely function on my car? Would there be a significant decline in handling performance?

Hello Sajeev, David Holzman says I should write to you about my Mazda concerns.

1. Concern #1. In two out of three dealers there was significant rust at the center of the wheels due to the wheel caps not having been put on. I only took three pictures, but essentially: at New Country Mazda in Saratoga Springs NY 100% of the Mazdas had no wheelcaps on in the lot and were all showing various degrees of rust. That includes the one in the showroom, you can see it in the pic with the tile floor.

Good afternoon Sajeev,

Read your latest and I’m determined to help you out. I recently had a bone-stock 87 CRX Si follow me home from an impound auction and, if I can get the damn thing through an Ontario Safety Inspection, I’ll let TTAC’s very own Derek K drive it.

Therein lies the rub, or brake rub really. The front discs were rubbing, a lot. Constant grinding sound as the wheels turn. I have since removed/lubricated the caliper sliders (they were a bit stuck from sitting) and measured the discs and pads using a measuring tape and straight edge, everything is above min specs.

With the pin lube the grinding noise has abated somewhat but continues, worst is passenger side.

The discs don’t feel warped (no front shudder under hard braking).

Your thoughts?

Hi Sajeev,

I’ve had a 2009 Dodge Caliber SRT4 for a few years and it’s coming up to its first all-around brake job at 50,000 miles / 80,000 km (I drive like a granny). I work at a dealership (different brand) but can get parts at a bit of a discount. Still, OEM brakes + pads on this thing are $980+tax Canadian. From what I’ve seen I can get aftermarket ones for a quarter of that. One of the mechanics here suggests I put on OEM pads and aftermarket discs.
