Boxster '99 Brake Replacement

[vza]

Hi, I'm replacing pads and rotors all around on my 99 boxster base. In Bentley and 101 Projects there is no mention of cleaning the calipers with brake cleaner. Also no mention of applying brake lube or where to apply it (the little packet that comes w/ Brakes). Is cleaning and lube not recommended on these cars. I'm using the Power Stop Z23 sport upgrade w/ slotted and cross cut rotors. Hope it's a wise choice. Thanks V

Our brakes are monoblock (as opposed to floating) so there are much less sliding parts. You can still clean the caliper/dust boot. Other than that, you can coat the brake pad pin and the small locking pin very lightly with antiseize.

Hi Ahsai, OK ..so am I  applying it to the corners of the pad where there's a little cut outs? I believe thats where the clip and the pin meet the pad as a friction points. OK to use brake cleaner? Ever hear anything about powerstop? BTW been running the car with NO CEL's no pendings even. Thanks again for the help.v

[Ahsai]

That's great to hear. Yes, you can apply some where the pads contact the sliding pin. Brake cleaner is OK because it's safe for rubber and the paint on the caliper also.

I've never heard of powerstop. If you go aftermarket you may want to stay with the more well known ones such as Zimmerman, Brembo, Textar, Akebono, etc to avoid squeaking.

Emmm....we'll see what happens!! Does my '99 use the brake dampers??v

[Ahsai]

Not too sure. I can't find dampers for your model (seems to start in MY2000).

Hi All, 99 Boxster base.Replaced front rotors and pads. It seems as though my brakes really didn't improve much. Actually there is no real difference other than some squeal.  I feel if I had to make an immediate short stop I just wouldn't be able to. It feels as though I don't have power brakes. The pedal height seems normal and not spongy. I have TC (Traction Control?) in car and read you need a PTS2 to bleed brakes in order to open a valve so the calipers remained attached during the work and brakes were not bleed because the system was not opened anyway. Any thoughts thanks V

Try this. Turn off the engine and pump your brakes 5 to 6 times. The pedal should feel harder and have shorter stroke everytime you pump it. If that's the case, I think your brake booster is working. If you have air in the system, the brake pedal should feel spongy and should be quite obvious.

 

I have no experience with your brand of brake pads but the feel and stopping power varies greatly with pad material.

You do not need to use a PST II to properly bleed the brakes, that only becomes necessary if you get air into the control network.

OK, So I can bleed the brakes with the 'TC' option installed. I will pump the brakes w car not running see what happens. ceramic/carbon fiber pads. Thanks guys....V

I pumped the brake ped with car off. It's high at the start and gets higher as I pump but in very small increments v
