Parts for the Rear calliper overhaul.


As it involves the automatic adjuster for the parking brake mechanism, bit more parts required than the Front side.

Again, double checking the smooth operation of the piston as well as the seating of the dust boot.

    Hi Kaz,
    I noticed that you are using the brake spring compressor 07HAE-SG00100 as recommended by the service manual to do this job. Is this tool essential for this job?

    Also according to the manual you need to use a commercially available "locknut wrench" to remove the piston. What is one of those? Is it essential?

    Thanks

    Hi, Peter.

    You need to press down the clearance adjuster spring while removing the circlip and as the spring rate is not that high, you can probably make your own SST.
    However, this SST is not that expensive (about US$50, I think) and it is very important to press down the cone shaped washer evenly in order to set the circlip into the groove properly, I would recommend getting this SST.


    I was not sure what ‘Locknut Wrench’ meant when I first read your comment so checked the English workshop manual.
    It is the ‘Brake Piston Wind-Back Tool’. Again, it is not that expensive so if you are planning to overhaul the Rear calliper by yourself, just get the one with the correct pin size from your local tool shop.

    Alternatively, some people managed to rotate the piston by inserting the metal shaft of pry bar, screw driver, etc into the ‘ + ‘ shaped channel at the piston surface. Not recommended but can be done. Probably, you can get the idea on what I'm talking about by looking at the 3rd and 4th photo above.
