What year imp did you do this brake conversion on ?, thanks, Mike Becker ----- Original Message ----- From: <TheTanSedan@xxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Thursday, April 04, 2002 1:58 PM Subject: Re: IML: Disc Brake Conversion > The generally recommended course of action is to remove everyting from one > specific donor car : spindles, rotors, calipers, m/cylinder, hoses, booster, > proportioning valve, etc. Even if the parts are no good, one has a basis to > compare the "new" pieces against, e.g., brake hoses.
